Would an otherwise original surface Morgan dollar get encapsulated if it has a

prominent rust spot, a fleck, in the field on on the devices?

    The silver-copper alloy shouldn't oxidize in that manner. If there is corrosion, it is probably from some other reaction. Show an image so we can try to determine what you are referring to. There are a lot of other things that are possible that are acceptable, from carbon spots to planchet defects.

    Well, it is like red like rust, isn't it? Wouldn't think ferric oxide would be growing on a Morgan. Have you tried wiping it off with a moist towelette™? Been eating chili whilst looking at your coins?

    that's too insignificant to body-bag the coin.

    I've seen coins in PCGS holders with those red spots before - I don't think it would be a problem but you never know what side of the bed a grader will wake up on... problem-free coins have been bagged before image

    Thanks guys,
    Golden Eye, That's good to know.
    Pharmer, I'm thinking about buying this piece.
    I bet the seller would have wiped off whatever (chili indeed!). So would that be ferric oxide in the planchet?

    Don't see how it could be, but rust is ferric oxide and ferric hydroxide, I believe.

    I wouldn't suggest wiping it. Look at it closely with a loupe, at an angle. Probably just a small toning spot. Not attractive but also not a baggable offense. An acetone dip followed by a distilled water rinse and pat dry with a lintfree cloth should handle it if it is some organic debris by chance. Never hurts.

    You need not rinse in distilled water as acetone will complete evaporate without leaving any residue. In fact, many folks recommend dipping in acetone to remove dip residue.
