https://www.cointalk.com/threads/can-anyone-tell-me-what-this-coin-is.270755/#post-2274841 I put it in the wrong forum
Here. I cropped your images and put both pictures side by side to help with assessment. But whatever it turns out to be, I can tell you the process of mounting it probably did irreparable harm to the coin...assuming that's what it is and not a token. Good luck!
Sorry, I don't recognize it. The portrait looks Roman Republic-ish, but the reverse legend does not look like it belongs on a Roman coin of any era. I am probably wrong so wait till others reply.
The Greek letters at the top of the left picture are the clue. These read "ABDE" for Abdera in Trace, Greece. What's below the letters will than be the common logo of Abdera, a crouching griffin. The letters below the griffin will be the name of the issuing authority. Can't read this and it is needed for definite attribution as there are many different types of this general design.
Yup. That is a griffin from Abdera and should be silver although the photo looks gold. The other side is possibly this but with a bankers mark on the jaw. Pretty worn out coin regardless or a copy. https://www.numisbids.com/n.php?p=lot&sid=840&lot=46
Good eye, THC and 4to2! I didn't recognize the griffin at first but you've found the match. I suspect the coin is real but worn and polished/modified to better fit the bezel. As for the metal, in the picture it looks silver. The bezel looks gold, but it is possible that the image's color is off.
Here is my Thrace, Abdera gryphon example ... sure, it's not exactly the same as the OP coin-type, but you get the gist, eh?
I would not call the coin worn out. The poor detail on the griffin is due to the flat spot created by the bold strike of the countermark on the neck of the obverse head. I would not remove it from the mount because of what Sallent pointed out as irreparable harm.
ahaha, nice anyway ... here is an example far nicer than yours for $65 https://cngcoins.com/Coin.aspx?CoinID=285925
That's different then mine but similar, I haven't been able to find any other pictures of the one I have, don't know if that means anything or not
Not much different. I think yours just has a banker's mark at the bottom of the portrait that kind of destroys the portrait a little bit, and no square around the portrait, other than that they seem to be very similar. if your only interest in ancients is to sell this, move on. Stick it in a drawer and forget it. The value of that coin is pretty much shot with that gold pendant mounting around it. But if you are genuinely interested in those coins, $65 is not a bad price for a nice sample of one. I would consider it if I were you. it would not be a bad start to an ancient coin collection.
http://www.acsearch.info/search.html?id=14297 I believe the above bronze has the same countermark. There never was an answer about the size but the loop on the bezel suggests it is a hemidrachm rather than tetradrachm. Before it was mounted, it was an interesting and valuable coin but if it was soldered in the ring that drops by 90% on the coin market. If removed and the coins show damage as it probably would the jewelry value is ruined. Some of us collect countermarked coins but I suspect the family story might make keeping it the best answer. Repaired coins and broken jewelry are not high demand items even if the starting point was a desirable, rare even, coin.
