Benefactor robinjojo Posted February 13, 2023 · Benefactor Benefactor Share Posted February 13, 2023 (edited) Maybe it's not a corner. It is a nicely alliterative title, better than Cob Octagon or Cob Triangle. I thought it would be nice to have a thread dedicated to these fascinating and historical coins, a venue where I can share my enthusiasm for these coin and one where we can share information and coins, perhaps instilling the collecting bug in some of you who are interested and need just a nudge to become full blown cob collectors. I have accumulated and documented many cobs over the past 40 plus years. I have posted many here and at CoinTalk. My postings are rather messy, not very systematic, jumping from one mint or king as I pull coins for photographing. Please bear with me, and I hope that the coins posted herein are both entertaining and informative. I'll start with coins that I have photographed on file. I'll continue to post and please share your cobs. If you have any questions, I will try to answer them to the best of my knowledge.

Benefactor robinjojo Posted February 17, 2023 · Benefactor Author Benefactor Share Posted February 17, 2023 (edited) Thanks, everyone! Here are the Colombia cobs on file. Colombia, like Brazil, was gold rich and silver poor, as exemplified by the large number of gold coins and comparatively fewer silver coins on the market for the colonial period. The two mints in Colombia were Santa Fe de Bogota and Cartagena de Indies. The later is a fabled city, whose port, the fortresses and the monuments are UNESCO heritage sites. The fortress of Cartagena, Colombia, lit up at night. The cobs that I own are the cumulative result of buying these elusive coins over decades. Colombia, Cartagena, 8 reales, Philip IV, (RN)E to left of shield, 1629. KM 3.4 27.3 grams The first cobs produced at both mints was the shield type, introduced in 1622 by the Bogota mint, using dies from Spain. The shield coinage was sporadic, especially for silver coinage. Distinguishing Colombian cobs from other cobs, especially those from Spain, can be challenging at times. The keys to look for are the mint and assayer marks, which are sometimes off the flan or incomplete due to striking anomalies. How do we know that this is a cob from Cartagena? Looking to the left of the shield, flatly struck are a N (very weak) and an E, or (R)NE, running vertically. Cartagena at this time use the RN,. Very confusing! However, the assayer E worked at Cartagena, so, based on that information the coin was minted in Cartagena in 1629. That date is speculative on my part. It runs on the reverse from around 10 to between 11 and 12 o'clock. The 1 and 6 (faint) are legible, but due to a bend in the flan, made at the mint, the 2 and 9 are extremely weak and can only be detected with high magnification. Even then those last two numerals are not conclusive. This is my only Colombian gold cob, a 2 escudos from Bogota. Colombia, Bogota, 2 escudos, Philip IV, NRA, circa 1630s. Purchased in the early 1990s from a local coin dealer, Austin and Company. 6.7 grams Here, we have a coin that has a minor die shift, struck from rusted dies, and with weakly struck mint and assayer marks. Still, it is possible to see the N, part of the R and a very weak A, NRA - NR for Nuevo Reino de Granada, the name of the colony, and the A for the assayer. The date on this coin runs from about 9 to around 10 o'clock. The 1 and the bottom of the 6 are visible, but the remainder of the date is off the flan, as is very often the case with these coins. In the 1650s Colombian cobs switched, along with Potosi and Lima to the pillars and waves design that remined for the duration of this coinage. Colombia, Bogota, 8 reales, Philip IV, 1660s, PoRS NR. Purchased from Superior Galleries in the early 1990s. KM 7.1 27.1 grams I was fortunate to win this coin in a Superior auction. The pillars and waves cobs from Bogota are quite expensive and often salvaged. This coin, with its slightly oxidized surfaces might be from a salvage, but it is full weight and attractive in its crude way, with strong centers on both sides. With cobs in general, collectors will pay more for coins with complete or nearly complete center strikes. This cob shows typical areas of strength and weakness in the strike, so even with the obverse date situated towards the coin's center, the last two numerals are muddled and weak, the last one really not visible. For a while I though the date was 1665. I am pretty sure that the third numeral is a 6. With the help of Krause, that puts the coin in the period of 1663-1665. I think that I have one more cob, a shield type from Bogota that I need to photograph. Next up will be the cobs of Mexico on file.

Benefactor robinjojo Posted March 2, 2023 · Benefactor Author Benefactor Share Posted March 2, 2023 (edited) Today I thought I'd move on to the mint of Mexico City, the oldest mint in the Americas, founded on May 11, 1535. As such this mint has a rich legacy and longstanding impact on the economic and political history of Mexico, North America, Europe and much of the rest of the world. It is difficult, at least for me, to say which mint had the highest production of cobs, Mexico or Potosi? It seems almost a dead heat in my view, as both mints had continuous production, without the interruptions experienced by Lima or the extremely sporadic production of Bogota and Cartagena, Colombia. I guess I'd give the edge to Potosi, since cob production continued until 1773. Mexico began ending cob production with the introduction of the milled pillar and waves coinage in 1732, with the last cob type appearing in 1734. Here are some of the main types of Mexican cobs that show up on the market. I have other cobs that I will photograph and post in this thread. The first pillars cobs, the "Charles and Johanna" type, in the denominations of 2, 4 and 8 reales began when the mint was established. There are two distinct types: coins with waves and coins without waves. The latter are by far the rarer of the two varieties. Only a very few 8 reales of the no waves design were produced, making these coins exceedingly rare as the first silver dollar produced in the Americas. One example sold at auction for $373,750, the highest price ever paid for a Spanish colonial coin at the time. It could still be the record. My first Mexican cob, without waves, is far humbler, but it is a pretty one. Mexico, Charles ,I 4 reales, No Date (1536-1538), Assayer R (Francisco del Rincon). Purchased from Rick Ponterio. KM-16; Nesmith-6c 13.47 grams The pillars without waves design was modified to include waves around 1542, with production running until around 1571, when the shield design was adopted, replacing the pillars and waves, under Philip II. Of the two pillars types, this design is far more common, although locating a nice example is no mean feat. Mexico., Philip II, 4 reales, circa 1570, assayer L (Luis Rodriguez). KM 0018 13.8 grams The assayer can be found on this coin to the left of the shield. The pillars and waves cobs, including the 1/2, 1, 2 and 4 reales cobs, can have mint marks and assayer marks in various positions. Shield types (this basic design remained largely unaltered to the end of cob production) Following the pillars cobs, silver production and mint capacity allowed for the reintroduction of 8 reales cobs. Mexico, Philip II,8 reales, No Date (circa 1571-1578), Assayer O (Bernardo de Onate and Luis de Onate). Purchased from Rick Ponterio. KM 43 27.2 grams Assayer O appears below the oM mint mark, to the left of the shield. This will remain the assayer's position on cob coinage for 2, 4 and 8 reales for the duration of coinage, with a few minor exceptions. Mexico, Philip III, 8 reales, No Date (1599-1607), Assayer F (Francisco de Morales). Ex Richard Long 12-1982 KM 44.1 Seed coin for fake Philip III 8 reales, 27.4 grams The undated cobs of Philip II and Philip III are quite difficult to distinguish if not enough peripheral information is visible. However, as a rule of thumb, the inner part of the central crown above the shield has vertical lines for Philip III. Philip II cobs lack these lines. Another interesting aspect of this coin is that it was used as the seed coin, to produce the casting mold, for replica Philip III Mexico 8 reales cobs by a couple of brothers in Mexico City back in the 1960s. These fakes sometimes surface, and they can be tricky to detect since they are often made of good silver. Here is an example, courtesy of Daniel Sedwick. Note how the flan cracks are filled in and not sharp, and overall detail is flat. The color is also off, indicating lower silver content, as indeed the weight indicates. Still, as copies the quality is not bad. Fake Mexico Philip III 8 reales. 24.8 grams Dated coinage began in 1607. The date, when visible, runs from roughly 9 o'clock to 11 o'clock, but that can vary. Unlike Potosi, the Mexican cobs only have one position for the date, so if it is off the flan or poorly struck and illegible, you're out of luck. Often times the date is only partially visible and muddled, leading one to engage in some detective work and an educated guess. Mexico, Philip IV, 8 reales 1667, Assayer G over P. Musi River Sumatra salvage. KM 45 25.4 grams As coinage under Philip IV progressed, the flans became less round, with some very "barrel" shaped. The year 1665 saw the passing of Philip IV and the ascension of Charles II to the throne of Spain, under a regency for many years. Mexico began to mint cobs with his name in 1667. Over the years of his reign, the quality of the coinage declined dramatically. Indeed his coinage is easily the crudest in every respect: oddly shaped flans, crude dies and often times horrendous strikes. Mexico, Charles II, 8 reales, (166)9, Assayer G (Geronimo Baccera). Purchased from the Mexican Coin Company KM 46 26.7 grams Here's a 4 reales of Charles II, Mexico, that has a flan shaped like a cat or some other animal. Mexico, Charles II, 4 reales, date not visible (circa 1690s), Assayer (L). KM 39 13.7 grams While the early cobs of Philip V continued the trend for odd shaped flans, his later cobs became often square or rectangular shaped. With is cobs comes the Bourbon shield of three fleur des Lis in the middle of the obverse shield. Mexico, Philip V, 8 reales 1710, Assayer J (Jose Eustaquio de Leon). A bird-shaped flan. From Sedwick Treasure Auction 26, lot 405. KM 47; S-M22; CT-unlisted 26.77 grams Mexico, Philip V, 8 reales Philip, 1730, Assayer F (Felipe Rivas Angulo). Acapulco Hoard. KM 47a 27.06 grams By the 1720s to early 1730s the flan became very square and chunky. Finally, for this post, is a final hybrid cob, a beautiful coin, that was produced for a couple of years 1733-1734, contemporaneously with the milled pillar waves coinage. These coin are called "kilpped" cobs, due to the angular edges. Indeed it is hard to tell if these coins were hand or machine struck. The fans are irregular, similar to cobs, but the strikes are often so uniform, one can see how only a press was used. The dies are unique to this type. They were not used to produce milled coins Mexico Philip V 8 reales, 1733 MF, 'klippe' type. Ex Ponterio Auction,, COIN, June 1988. KM 48 27.3 grams Edit: I forgot to include my one 8 escudos from Mexico. The old brain is going fast! Mexico, Philip V, 8 escudos, 1713 J (Jose Eustaquio de Leon). Purchased at Long Beach, January 1990 KM 57.1 26.96g To bring this post full circle, here's a milled 1733 8 reales, the second year of the new design, actually a revival of the pillars and waves design of nearly 200 years prior. Mexico, Philip V, 8 reales, 1733 F, milled pillars and waves, Marathon Florida find. From the 1733 Fleet. KM 103 25.70 grams This coin, purchased over 20 years ago from Daniel Sedwick, is said to have been found under a nineteenth century building in the Florida Keys, at Marathon. The small structure was and old wooden building about 14 feet by 20 feet. The coin was lying in the sand underneath.

Benefactor robinjojo Posted May 31 · Benefactor Author Benefactor Share Posted May 31 (edited) I thought I'd post a few more coins in the hope that other members might be interested in adding a cob or two. Apparently collecting Spanish hammered coinage is an area not frequented by forum members, but perhaps this will change over time. These coins are recent purchases from Sedwick's Treasure Auction 35, held last month. Potosi, Philip IV, 8 reales, 1634 T. Full date. Sedwick Treasure Auction 35, lot 924. KM 19a 27.00 grams First, we have an 8 reales from Potosi, dated 1634, assay T (Juan Ximenez de Tapia). When the coins of this assayer for the period 1629-1639 appeared, they represented an improvement in quality over the extremely crude Potosi cobs of the 1620s. This did not last very long. As the 1630s progressed the strikes, flans and dies of this coinage took on the crude, makeshift appearances preceding issues. While the weights generally tended to be within standard, basic information is often missing on any given coin from this period. This example, however, does possess one very important feature: a full date. This was accomplished by at least two strikes on the reverse (cross side). While not the prettiest cob on the block, its crude minting did produce an unambiguous date, along with a nearly full shield, assayer and mint marks. Potosi, 8 reales, Philip IV, (16)41 TR (Pedro Trevino). Sedwick Treasure Auction 35, lot 926. KM 19a 26.44 grams This coin has an interesting and rare feature on the obverse. The Flanders-Tirol in bottom half replaced by the shield of Portugal (weak but certain). According to Bolivian researcher Daniel Oropeza Alba, this strange issue (more prominent on the Royals for this year) is linked to a Portuguese neighborhood within Potosí known as the "Lusitanos" that suffered persecution and dispossession of property as a result of the Portuguese revolution of 1640, which ended Spanish control and restored the Portuguese throne under the Duke of Braganza (João IV) The lions and castles on the reverse are transposed, something that occurs with some frequency with the old style shield cobs of Potosi of the 17th century. The last half of the date is quite bold. The last cob out of this auction is from Seville, the most prolific of the Spanish mainland mints. Spain, 8 reales, Philip IV, (16)30/29 R (name unknown), Seville. Sedwick Treasure Auction 35, lot 1417. KM 80 27.03 grams This coin exhibits typical crudeness in strike. The overdate is quite bold, especially with the 3/2 and as such is rare, apparently the only example showing 30/29. So, your comments and questions are always welcome. Please post your cobs or other Spanish colonial and mainland coins, if you wish. Thanks! Edited June 1 by robinjojo 4 Quote Link to comment Share on other sites More sharing options...
