A majority of my dad’s collection over 100 pieces of bullion silver all looks like that Peace dollar slimy green. I haven’t felt like pricing out acetone by the 55-gallon drum to deal with them. (View Post)

Sample slabs might be worthwhile. (View Post)

Looks more like dip residue that wasn't properly rinsed and is turning in the holders. (View Post)

Looks like photography lighting related as in hand I believe it's not black but bright copper like the tiny contact mark under ER in America below. (View Post)

Thanks... Ricko, I bet won't say the same! :p (View Post)
