My MIL finally convinced her to let me look at them. She's been keeping them in a tiny cedar chest - I know this isn't good, and of the ones that are silver, many are turning green or white/grey. She has about 30 of the 40% Kennedys, a single 90% Kennedy, and 5 old dollars. One is an 1879 Morgan (no mint mark) and the other 4 are Peace dollars, (3 1922's and a 1925). The Morgan is pretty dark, but there are some shades of blue toning around the edges. I'm wondering what to tell her about the value of the 40% Kennedys. I know the silver content is about $2.40/ea, but I wouldn't want to pay that myself, and I know taking them to a Gold/Silver store she wouldn't get anywhere near that. Anything special about the Morgan? Doesn't look like it to me, except slightly the toning, but the pictures don't really show it that well.
