New to this forum, In the last few weeks I have searched through adout $200-250 in pennies. Too many wheaties, 68-74 S's, BU Cents etc. to list. So I will list what I have found that is interesting.
1. 1968 S Heavy doubling of entire date
looks almost identical to the example 2/3 the way down this page.

2. 1970 S medium doubling south/southwest of the 970 on the date
3. 1999 "P" minor- medium doubling southwest of "ONE CENT" of the reverse
4 1990 "P" minor doubling of TED STATES towards to rim of the coin
I can find no information of these on coppercoins.com , conecaonline.org , lincolncentresource.com or the Web in gerenal.
