I'm sure it's too late now, but did you look inside the upper loop of the R for an Omega? The 1882 three dollar gold was the other coin that he did. An 1882 Omega counterfeit would be the correct weight an material so most of the machines used for detecting fake gold wouldn't catch it. I don't know but I would suspect an Omega coin would bring a premium, not over the the price of a genuine 1882, but probably a premium over the melt value.
