Official "Post A Counterstamp" Thread....

This one was a great puzzle but and it gave me fits figuring out the attribution. It arrived a while back in a kilo lot of international coins. It was filthy to the point of being unrecognizable and just appeared to be a damaged coin. I came across it a few days ago and realized that the damage might actually be a counterstamp. I gave it distilled water and acetone baths, but the crud remained. It took gentle scrubbing with a soft toothbrush to loosen the crud, and then it was returned to the acetone. Initially I thought that it was a chopmark. But I could tell that it wasn't silver, so if a chopmark it would mean "not silver". After the baths I could tell that it was an Ottoman Empire coin dated AH 1327 Regnal year 3 with a 4 in the denomination. Numista helped me figure that the host coin was Ottoman Empire 40 Para 1911. The tough part was figuring out the counterstamp. Internet searches finally turned up Hejaz, and Numista was able to confirm my determination. The stamp literally means "Hejaz".

A better view of the counterstamp. I think that this is the correct orientation.

Thank you, Errers! Solving a puzzle always brings a nice feeling of satisfaction.

Thank you, Dearborn! It was a pleasant surprise to find out that it wasn't just a damaged piece of junk but rather an interesting coin.

This is an ancient counterstamp. Back then, counterstamps were used to certify coinage for usage. The 2 counterstamps on this coin (TICA and AVG) were used by Tiberius in the the regions of Moesia and Thrace. I also have another counterstamped coin from the reign of Claudius I.

wow, that one is very nice!

That is a really cool coin, Seeker!
