    I think it went like this: Bidder 3 entered a prebid of 90 or 95. Prior to the sale, the only bid entered by Bidder 1 was a proxy bid of at least 120. That proxybid was initially triggered when the lot went on the block, at 100 to beat Bidder 3’s prebid. Then came your live bid, @ambr0zie, which triggered another increment on Bidder 1’s proxy. 

    Almost. Not bidder 3's bid was at 95, but there were two proxy bids, one at 95 and one at or above 120. We'll have to make an update to the bid history to show outbid proxy bids that raised the bidding level.

    As for the frozen screen, besides computer/browser problems, this can happen if your internet connection has a short hickup.

    Vykingship. I've been using them for maybe 5 years at this point and can only say good things about them. Others may be cheaper, particularly since Vykingship is based in a state with sales tax (Minnesota), but their customer service, reliability, and speed has made me a loyal customer.  

    I usually send cheap coins with their $13 "Asendia worldwide tracked" option or will consolidate a couple of expensive coins from different wins into a single FedEx package for $75 or so, which arrives in 2-3 days.

    That's very helpful, thank you very much!

  3. Congratulations on a great year, @AncientJoe! All wonderful coins. Here are a few more pedigrees in case you are not aware of them already.

    Your Maximianus Aureus is ex NGSA, Auction 13, Lot 13 (2021); Roma, Auction XX, Lot 681 (Long Valley River Collection, 2020); NAC, Auction 105, Lot 108 (2018); Gemini, Auction III, Lot 450 (2007). It's also supposedly (I didn't check) ex Tkalec, Auction 25 October 1996, Lot 264; Leu, Auction 65, Lot 480 (1996) and published in X. Calicó, Los Aureos Romanos (2002). NAC says it's also ex Leu, Auction 93, Lot 121 (Claude Vaudecrane Collection ["a perfectionist"], 2005) which, however, is wrong. Roma and NGSA copied the mistake.

    And your Nero is ex Künker, Auction 117, Lot 5040 (2006). Not very important since you found the Hirsch and Ball pedigrees, but just in case you want to have your records as complete as possible.

    I particularly like your Maximianus Aureus. One of my favorite coins is from the same series.

    Nice, interested to see the photos! And could you provide some info on the cleaning job? I have a coin with lovely surfaces but also some hard dirt on it which requires tools other then the wooden toothpick, and I would like to have cleaned. But I do not dare to do it myself! 

    Here is a picture taken with my smartphone (until I have better pictures). I had it cleaned by a professional in Germany. I usually send in half a dozen of coins and get them back after a month or two and get charged by hour. The last batch of 9 or 10 coins (including the Rhino) took them 11 hours to clean.

    I'm glad you had a stellar year despite the heavy competition!  Like many others here I love the rhino of course – looking forward to that new photo! – and wow, what a provenance on the Titus!  (Great coin too, excellent Minerva.)  Like @Sulla80 I wondered about the cornucopia/scales combo, I'm not sure I've seen that motif before. (Happy New Year to you too! 🙂) Great find on the wolf with cave, I hope you managed to snag that for a bargain because nobody else realized what it was.

    Thank you very much, @Severus Alexander! 🙂 The wolf with cave was indeed a bargain (at least IMO) as I was ready to bid quite a lot more for this rare piece. Van Heesch records two pieces in Vatican (#37 & 38) with Tiber left (another variation of this rare series), but none with Tiber right. Mine seems to be completely unrecorded.

    My favourite, though, is the Mercury/rooster.  I'm wondering... might Mercury have the features of a young Marcus Aurelius?

    image.jpeg.6931b8bd2bd073dc85a691d17f92b7cb.jpeg

    Yes, absolutely. By now I believe that all the anonymous fractions of that series were produced under A. Pius as many of the male gods (Jupiter, Tiber, Mars, Neptune) not infrequently bear the facial features of A. Pius. Mercury does indeed on many coins look like the young Marcus Aurelius. On one particular coin, Mercury looks just like Hadrian. I think it's very probably that they were minted in the first 10 or so years of A. Pius' reign.

    Of course there's other evidence like the wolf in cave that first appeared on coins of A. Pius or the legend TEMPORVM FELICITAS that first appeared under A. Pius and is related to the four seasons Quadrantes.

  5. Thank you everyone for the nice comments 🙂 

    On 12/28/2022 at 1:42 PM, Sulla80 said:

    the Hadrian with scales on cornucopia I find particularly interesting - how would this have been read by an ancient recipient?  Aequitas? just distribution of abundance?

    That's a good question. Both the cornucopiae and the scales are typical attributes for Aequitas and Moneta. I would probably interpret it as something like "abundance/wealth to everyone", which makes a great New Year's wish. In that spirit, I wish everyone a prosperous New Year.

    Very interesting collecting theme, and some great additions, congratulations. Personally, I like the Domitian quadrans most. The Künker photo's don't do it justice, I imagine, it must a great piece in hand. 

    The picture of the coin is quite accurate, I'd say. However, I had it cleaned in the meantime and all the minor encrustations are now gone 🙂 I'll share a new picture as soon as I have it photographed.

    I was wondering who bought the Zeus Ammon tessera - it's an amazing piece! Have you been able to find any references for your tessera, or deduce what the winged object is? Mine seems to be unpublished and I'm curious if that's the case for yours as well.

    Thank you, @JeremyI haven't found anything that is remotely similar until now. I assume it's unpublished as well.

  7. 2022 has been an unexpected successful year in terms of finding new coins for my fractions collection. Although competition was extremely strong on many of the coins I've bought, I am very happy with every single coin a did manage to buy.

    The "four seasons" quadrans series is somewhat controversial, with some claiming the young boy is a representation of Commodus' younger brother Annius Verus, and others maintaining that he is nothing more than an allegory, and possibly that the coins were minted as early as the time of Trajan or Hadrian. Regardless, this "Winter" quadrans is quite rare and I am thrilled to have it, whether it represents Annius Verus or not.

    Not as controversial as you think. It's widely accepted today that the four different types represent the four seasons rather than Annius Verus. Van Heesch conclusively refuted Cohen's thesis that this was Annius Verus in his article "UNE REPRÉSENTATION REMARQUABLE DES QUATRE SAISONS SUR SEMISSES DE L'ÉPOQUE ANTONINIENNE" (translated from French to English):

    It is unlikely to be Annius Verus. There is not only a resemblance with this prince but the portraits can also be compared with those appearing on some aurei of Antoninus Pius and with the heads of Commodus caesar, Galerius Antoninus, Geta etc. All these heads of young boys are very similar. Moreover, semisses and quadrantes were no longer issued during the reign of Marcus Aurelius.

    Your piece is particularly interesting because it combines the obverse of the winter type (veiled head, crowned with reeds) with the reverse of the spring type (wreath of flowers). There are only very few pieces where the obverses and reverses have been incorrectly combined.

     

    Edit:

    I think that the four seasons Quadrantes were issued under A. Pius (like possibly all anonymous Quadrantes), the first emperor issuing coins with the legend TEMPORVM FELICITAS and showing the same youthful heads of two boys on two crossed cornucopiae:

    3107991.m.jpg.5d64263577f77b3afad1219de1ef3d77.jpg

    Commodus later adopted the same legend on a medallion depicting all four seasons in the same image for the first time on a coin:

  9. Just recently discovered another old provenance. Not as impressive as the d'Este/Gonzaga provenance, but still very nice:

  12. Well in that case I'd simply use a list of names of the kings, magistrates and/or issuers that are of interest. For example:

    Alexandria Troas (Lysimachus Antiochus)

    Or if you are interested in certain denominations (e.g. Tetradrachms), add those too. If your looking for bronze, use "AE" (including the quotation marks). This all helps to narrow down your search. Once you get used to the search syntax, it's quite easy to get exactly what you're looking for 😉

    Nonetheless, thank you very much for your inputs. The features you suggested would certainly be nice to have and I'll see what I can do.

    None taken 🙂

    Two recent examples are "Alexandria Troas" and "Ilion".

    If you only care about the greek coins and not about the roman provincial issues, use the following search term:

    Alexandria Troas ("bc" "b.c." "bce" "b.c.e." "v. chr." "avant j." "a.c." "ac") -(colon pseudo autonom "ad" "a.d." "n. chr.")

    Use the city name you are interested in and add two search groups, one positive, one negative. The positive group contains all terms of which at least one should be present in a result. The negative group contains all words that must not be present in a result (all of them would be associated with roman provincial coins). Use quotation marks where you want to have an exact match and no quotation marks when the term is either unique or may continue (the wildcard is added to all terms that aren't in quotation marks by default). Your results may still contain a few provincial issues, but most will be greek coins.

    Here are the results:

    Alexandria Troas (2168 results)
    Alexandria Troas ("bc" "b.c." "bce" "b.c.e." "v. chr." "avant j." "a.c." "ac") -(colon pseudo autonom "ad" "a.d." "n. chr.") (313 results)

  14. Please correct me if I am wrong, but if you use regular expressions to get data to train an ML/AI model, the model will only (or mainly) work for records that follow the same regular expressions. Amazon had that exact problem with their facial detection app where they used mainly faces of white people to train the model. The model then, unsurprisingly, only worked well for white people.

    I would use a pre-trained model (e.g. GPT-3) on a few thousand random records, verify/correct them manually and then train a custom model.

    More difficult than extracting the data is normalizing it (differnet languages, spelling, notation, etc.) so that it becomes usefull.

    Back in 2016 I was volunteering for coinproject.com by writing a program that could read freeform auction record text from JSON files and understand it enough to create the kinds of metadata records CoinProject was using for its search feature.

    It was able to get about 98% understanding of the coin descriptions by applying "regular expressions" to human text written by the catalogers at Gitbud and Solidus.  For example, for Roman Imperial I was getting the emperor and his reign using this:

    •     '^(?P<issuer>[A-Z][a-z]+ [A-Z][a-z]+) \((?P<daterange>[0-9]+-[0-9]+)\)\.',    # Emp Emp (123-456)
    •     '^(?P<issuer>[A-Z][a-z]+ [A-Za-z]+)\. \((?P<daterange>[0-9]+-[0-9]+) ?\)\.',  # Emp. (123-456 )
    •     '^(?P<issuer>[A-Z]+) \((?P<daterange>[0-9]+ BC-AD [0-9]+)\)\.',                     # EMP (123 BC-AD 456)
    •     '^[A-Z ]+\. Minted under (?P<issuer>[A-Z ]+) \((?P<daterange>[0-9]+-[0-9]+)\)\.',    # EMP. Minted under EMP (123-456).
    •     '^(?P<issuer>[A-Z ]+) \((?P<daterange>[0-9]+-[0-9]+ AD)\)\.',                          # EMP (123-456 AD).
    •     '^(?P<issuer>[A-Z ]+) \((?P<daterange>[0-9]+)\)\.',                                             # EMP (123).
    •     '^(?P<issuer>[A-Z ]+) \(Died (?P<daterange>[0-9]+)\)\.',                                    # EMP (Died 123).
    •     '^(?P<issuer>[A-Z ]+)\. \(Died (?P<daterange>[0-9]+)\)\.',                                  # EMP. (Died 123).
    •     '^(?P<issuer>[A-Z ]+) \(Died AD (?P<daterange>[0-9]+)\)\.',                              # EMP (Died AD 123).
    •     '^(?P<issuer>[A-Z ]+) \(AD (?P<daterange>[0-9]+[ \?]?- ?[0-9]+)\)\.',               # EMP (AD 123-456).
    •     '^[A-Z ]+: (?P<issuer>[A-Z ]+) \((?P<daterange>[0-9]+-[0-9]+) AD\)\.',            # EMP: EMP (123-456 AD).
    •     '^(?P<issuer>[A-Z ]+)\. Wife of [A-Z][a-z]+\. \((?P<daterange>[0-9]+-[0-9]+)\)\.',   # EMP.  Wife of EMP. (123-456).
    •     '^[A-Z ]+\([0-9]+-[0-9]+\)\. Minted under (?P<issuer>[A-Z ]+) \((?P<daterange>[0-9]+-[0-9]+)\)\.',    # EMP (123-456). Minted under EMP (123-456).

    I had other patterns to extract Greek cities, denominations, and issue years.

    Most of the time was figuring out the other 2%.  Today I would just focus on the 98% I understood, and perhaps later use the programmatically extracted data to train an AI to guess at the others.

    Thank you very much @Ed Snible for providing your regular expressions. The problem is that I don't have time to write individual regular expressions for each company, language and numismatic area, which would take weeks and weeks of work alone. I would need one (or no more than a few) that is robust enough to cover at least 95% of all 10 million records. A well trained ML/AI model would most probably be more effective and robust.
