Coin identification

Hi I have recently started clearing out my nans draw and found a coin converted into a necklace charm and was just wondering if you could help me find out the history and value of the coin.

Hi would you happen to know the value I can’t see it on the identification of the coin.

just search it on ebay

There's an uncirculated one at MA Shops for 865 euros, but yours is worn and possible soldered to the bezel. I'd say you could probably get $150-$200 for it, but that's mostly a guess. Link below.

There were a couple of olmutz thalers in the ebay sold listings, similar in appearance but different years/types. They sold for ~$275 and ~$280, but they have less wear than yours. Link below.

Hope this helps.
