Seems to me I already read about this discovery quite awhile ago.
The best I've ever found is a sticky 1972 quarter in my van's ashtray just when I needed one more quarter for the laundromat. A miracle!
Something about this seems familiar to me, too. Wasn't there something a few months back on the G&G list about a Roman coin discovery in Britain? I just looked in my files but I don't seem to have copied that one; maybe somebody else remembers it.
