    I purchased some Silver American Eagles at the end of 2015. As a experiment I put one away. I placed it and a Morgan Dollar behind the printer leaning on the back panel on my computer desk. I removed it last year. Direct sunlight, water, etc. never came near the coins. Here's what they looked like after almost 4 years. I put them in flips last summer and no further changes were seen. The SAE toned more than the Morgan. Comments? galaxy 319 (2).jpg galaxy 320 (2).jpg galaxy 321 (2).jpg

    Interesting scientific experiment. I would suspect a few things. One, the ASE is .999 silver while the Morgan is 90% and 10% copper-nickel. Which may explain the dramatic shade difference of an otherwise same color. Two things perhaps explain the toning. Heat from the printer and/or dust particle from the air building up on the surface. A third option might be, are you a smoker?

    The water spots on the Eagle may suggest an improper rinse which may, or may not, affect the toning. ~ Chris

    Meh, nice but no cigar. I think maybe more years would be nice but then again, maybe not. Nice try though! :D

    I've never dipped, cleaned, altered, etc. a coin. Possibly the high humidity in the summer in Brooklyn has something to do with it. I never really looked at it all the time it was there. (Maybe once or twice in the time it was back there).IMO the coin is not attractive.

    They do have a nice golden glow to them.

    TM, put on your thinking cap! The Mint runs the planchets through a wash/rinse before they go to the coining chamber. Don't be so defensive! ~ Chris

    Please accept my apology. I thought you meant that I dipped the coin in Acetone, distilled water, or something else. Never thought about the mint doing it. :shame:
