CWBATX keep searching for the good ones there out there. After awhile you will know the RDV's like simple addition. I pretty much was ignorant my first quarter million I searched ( I'm referring here to myself not anyone else) I was too cheap to buy the reading materials and too sure of myself to bother seeking others help. Armed with a 8x loop and Cherrypickers book (an old 5TH edition) I set out to find the 1970 S FS-101.
It never happened. Today I know enough to have all the books on the
Lincoln Cent varietys, know there are hundreds of die varietys not in the CPG , and went and purchased some minor and major varietys for comparison. Brother when you do find a good one like a 1988 D RDV-006 I bet ya 50 cents you wont sell it, I just can't sell any of mine I worked too hard for the few dozen I have found. OK I would sell mine for $1,200.00 he he he.
Keep looking man and get them books these old timers have been asked these questions 10 zillion times and answered them all ( no wonder their cranky). No kidding keep searching their still out there. Good luck.
p.s. never ask me about the 1966
DDO FS-101 I get batty and loose my calm.
