I'm not a fan of fingerprints on coins (as if there is a fan base).
Some types of toning can be attractive, but I'm not feeling this one at all.
MatthewVincent mentions dipping, would a dip remove a print?
I ask because I have a common
Peace dollar, BU, with a print that I bought a long time ago
thinking acetone would remove it. That is when I found out about the permanence of fingerprints.
