Sue,
Unfortunately, the one thing I am sure of in caring for historic and
valuable coins is that you never, NEVER, ever clean them. Use no chemicals,
abrasives, or harsh language, no matter how non-invasive it might sound.
The value and importance of coins is in their condition as well as their
rarity, and even light "cleaning" can seriously damage their appearance and
value.
I would advise you leave them for a conservator to deal with, depite the
late date. Perhaps a small label explaining that to visitors.

Our mid-sized museum is preparing an exhibit of medium exchange featuring
currency and coinage. Some of the early colonial coins are extremely
tarnished and dark. I am unsure of how to safely “clean” or prepare these
early coins for display, knowing that some cleaners are quite harsh and
damaging. We do not have a conservator on staff and would not be able to
consult with one at this late date. I would appreciate any comments or
suggestions on cleaning methods for copper, silver and gold coins. Thank
you in advance.
