thanks guys.
the 1979 set has the fuzzy S and the 1981 set has the clear S.
i have a coin book from 1989 that explains the "S" difference. the clear set is listed for $100 each set, as per my 1989 book.
i'll shoot an e-mail to that website beetle. see if he's interested, then go from there.
really don't want to ebay them.
thanks again. be nice to get rid of them and get some x-mass cash
