Welcome to the forum @blake

I don't know about the rest of your coins, but that one is definitely a replica. Gold washed copper and sadly virtually worthless. Real gold does not tarnish, so that is the biggest giveaway even before we look at the low quality of the manufacture.

If you have others you are more confident of, please do post. Try to crop the pictures so we get the detail of the coin not acres of dull grey.
