Hello fellow Numista users!
I've got this coin from buying lots from some metal detector friends from Hungary a while ago ago and im unsure how to go about identifying it. im not even too sure if it is a currency item at all or what time frame it would even be in.



Its a castle on a base with dots around and something I can't figure out above it.
The reverse is completely blank, but i can share pictures if necessary.
Diameter is 12mm on the short and 14mm on the long end. (And 1mm thick)
I will be able to provide a weight tomorrow as i only have a precise scale at work.
It might very well be a coin weight or something of that kind, but we'll see what other users have to say :)
Thank you
