3" Saint-gaudens Commemorative Coin?

Shotzi21

I have a coin that looks exactly like the MCMVII saint-gaudens $20 double eagle (roman numerals included) except my coin measures 3" across, may be made from bronze or plated, has 29 rays coming from the sun on the back of the coin, and has the initials RO or RD under liberty's right foot. The coin was given to me from an older friend of mine for my son who said it was handed down to him from his father. Any information that anyone might have on this coin would be highly appreciated.

They are called a coaster or maybe a novelty.
It is NOT a coin.

These are novelties, I saw one at a swap meet a month ago for $2. They make these replicas of a lot of rare coins, I bought a giant 1877 Indian Head penny at the same swap meet.
