Found a damaged Agathokles 317-289 BC Tetradrachm in a french market

[Jan-Pieter V]

Hey everyone, first post here. I wanted to share a coin I found in a french street market for 1 euro. Sadly it's badly damaged and was probably used as a pendant. I don't even know if it's real or fake...
Some explanation about the coin I found online: https://www.cngcoins.com/Coin.aspx?CoinID=99640
However since finding it I can't stop reading about ancient coins so I think I found a new hobby

I wouldn't ever want to sell it because I found it myself and it's worth more to me than it's monetary value.

Discussion question: do coins with this amount of damage even have any monetary value to you? Or is it mostly sentimental value for the finder?

Have a nice day.

Hi Jan-Pieter, welcome to the forum. Others here will be able to tell you more or if it is a modern jewelry piece, but it would be helpful for you to post a photo of the other side and size and weight.

Looks much like cast copy. Edge shows some features of seam.
