Yee Haw! I Am a Wealthy Man! ;-)

Actually, now that I've had a chance to go through about half of the Joy
Fogel cents, I'm ready to say that there is no such thing as a bad penny
roll. ;-) 2 1960 BU's, a 1968-S, and more BU 1981-1984 cents than I've
seen in a long time! I only keep the very best and throw the rest of
those applicants back into commerce.
