Without knowing anything about coins (as you say),you supposed correctly that it would have been too nice to have the REAL THING in an old closet of your house... Indeed & unfortunately you have only 2 copies/replicas of 2 very valuable american ''private gold'' coins. Genuine were minted privately in Oregon 1849 & Colorado/Denver 1860.
One of your coins is marked with the letter R from ''replica''. The other one has not this letter but it is nevertheless also a copy. None of the 2 is made of gold,I think they are just gold plated. Probably the 2 coins stick to a magnet,they should not! Even if they do not stick,they still are not gold made but of another not-magnetic metal.
Here are photos of genuine coins of the 2 types:
Hi Stacy --
Yes. They appear to be replicas of very valuable coins,
Here's a picture of a genuine CLARK GRUBER piece which sold recently for $31,600 US dollars. This genuine coin weighs 18.07 grams. Take yours to a jeweler and get a weight accurate to plus/minus 0.1 gram. If your coin weighs between 17.8 and 18.2 grams, it may be genuine. If not, it's fake.
The Oregon Exchange coin is even more valuable if genuine. We have a page about these coins at this link:
