Good day to everyone, I needed help to identifying this coin as so far looks like is only one been found so far. This coin found in West Ukraine and been looking everywhere and is only one similar I found but with Heracles but not with Burebista king of Dacia. I will add this photo to.

I believe you have a fantasy piece based on this coin:

Don't know how to identify properly and value

Fantasy pieces are close to worthless. You could try asking a jeweler to test it to see if it's silver.

It is silver

For something like this, you might have better luck on a specialized forum.
