I just found a coin (cent through dollar) that looks like it is gold. What is it?
If your coin is a bright shiny deep gold color, it has probably been plated outside of the Mint (man-made). Such coins are sold in Sunday Supplement Ads for $3-$5 each as novelty items. If the edge of the coin is also gold, it has been plated. If the edge shows a nickel or copper color there is a possibility that you have a Mint Error coin. I would have to see the coin to determine its authenticity.
