Hi -
How have you been storing it? I once had some bronze coins in PVC that developed green crusts, not BD, probably verdigris. Since then I store everything in archival flips.

I
had it in what I thought was a Safe
Flip, but I guess it wasn't. I'm moving everything to them now (gotta buy a new batch from
FORVM). It's been in that old
flip for nearly 8 years. At first I thought it was retoning after it
had been cleaned, but it's lookin' ugly.
Anybody have any ideas as to what I can do?
Thanks again...
Mike
