(b) There are numerous minor 1972 doubled die varieties which have no extra value because of a Master Die having been doubled during hubbing. It is not known for sure how many working dies were produced from this doubled Master Die, but they were distributed to all three mints. If you need a ten power loupe to see the doubling on a 1972 penny, it probably isn't worth much because there are so many nice doubled dies in this year which are visible to the naked eye.
(c) Since 1994, some Lincoln Memorial Cents in high grades show traces of a removed mintmark on the coin. The cause is believed to be the removal of D and S mintmarks from dies or hubs which were originally intended to be sent to the branch mints, but which ended up being used at Philadelphia. They are worth a small premium over normal coins for that date.
If you are really serious about searching Lincoln Memorial Cents for profitable varieties, you should consider developing a method that allows you to systematically work your way through large numbers of coins in a short period of time. By performing the same sequence of steps over and over methodically, your search rate will improve greatly, and so will your success in finding varieties, because, like many other things, it boils down to a numbers game. The more pennies you search, the more varieties you'll find! See my page explaining the 8 Steps to Finding Variety Coins in Pocket Change.
