It is a replica of a US Gold Coin and not real .
If you get it XRF ed by a coin dealer or Jeweller
you will have your answer , cost about ten bucks .
I have seen similar pieces on my European Coin
buying trips . There are most likely gaming
counters ( Spielmarke) a possible creation by
Lauer , German manufacture .
Another possibility is a promo piece , made pre
Hobby Protection Act , thus not marked "Copy" .
One thing for sure ........ you are not rich LOL !
