Can anyone post a link that shows die markers or info about it? I believe I might have found one in circulation and under a magnify glass if is a very "crisp" strike and almost no imperfections other then miner circulation damage. I compared it to photos of 1 and they are almost identical but i think mine might be a earlier die state then the one I compared it to. It suck out like a sore thumb and looks lil very nice "mint luster".will have photos up soon but could use some info on it like die gouges or something
That's what has me confused because it was struck with a Philadelphia die instead of a san Fran die so it wasn't a proof die
All 1990 proof coins were struck in San Francisco. It is just that they missed punching the MM on a set of dies. It has happened more than once. Only the 1990 Lincoln, but 1968, 1970, 1973, and 1983 Dimes and the 1971 nickel.
