I was going through some more of my brother's stuff and found a coin I could not identify. Turns out it is a counterfeit 5 dollar gold piece. It is struck on a silver planchet and is as old as it dates. There are faint traces of gold plating left on it. Where a real 5 dollar gold coin weighs 8.359 grams this counterfeit only weighs 5.43 grams.
