Antimachos Tetradrachms Possible Die Match?

Recommended Posts

Recently my Leu wins finally shipped and after looking at my tetradrachms in hand, I think I have two Antimachos Tetradrachms with obverse die matches. I'm not sure if I'm imagining it, so I added a gif of the two coins overlaid on top of each other, and a side by side comparison. I've noticed the clumps of hair have the same shape and number. I compared them to different tetradrachms of Antimachos, and the hair clumps are different. The tip of the kausia touches the dotted border in both coins. I also think the ear, brow shape, forehead wrinkles, nose, and mouth look the same.

I did not plan on winning both of these coins, since they both have the same monogram, but it would be pretty neat if they were indeed a die match. Are die matches rare to find? I've compared about 10 other tetradrachms with these and they all have slightly different dies.

Those are definitely from the same die. Finding die matches varies greatly between different types of coinages. Some series are smaller and thus used fewer dies, making it more likely to find matches between two different coins. I'm not very familiar myself with the Greco-Bactrians or how large Antimachos emissions were, however judging by the amount of obverse die matches found on acsearch I would venture to say that this die is quite prevalent in the series as a whole.

Thanks for searching, makes a ton of sense. Turns out the 2nd coin in that list is one of my tetradrachms too! Not sure how they measured it to be 33 mm, it's slightly smaller than the 31 mm antimachos tetradrachm i have

Oh? That is a very decent provenance to add to the coin, congrats!

They're not all die matches there; the Hess Divo coin is a drachm. I wouldn't put too much stock in acsearch's premium search, I've seen very poor results from it especially from Baktria. In the recent die study, there were 354 tetradrachms for Antimachos I, so this is just a small proportion of his output.

Simon Glenn in his book Money and Power in Hellenistic Bactria records some 60 Obverse dies for Antimachos I. If @zadie is correct your coin appears to obverse 43 which is associated with reverse dies 139-144. This is an illustration of the book

and my coin

I too want to commend @zadie for his work. Many of these dies are very close and there are a lot of them with that monogram found on the reverse O 23/R 76 to O45/ R 148

You're right of course, it's unfortunate that you can't filter out single results with the image search. I'd like to highlight that all other hits from this search are obverse die matches to OP's coin. I've actually been pleasantly surprised by the capabilties of the image search function, having used it throughly during the last year due to the five free searches you get every day with premium.

I wish they would give use free users some of those searches... would certainly be a nice tool to have.

Outside of the die study, if you don't have them already I would recommend HGC 12, published by CNG, and Michael Mitchiner's "Indo-Greek and Indo-Scythian coinage" as references.
