Wulffy, I'm buying the P&D mint sets. They have the 4 commemorative Lincoln cents in copper. I will probably tell the shop to get me a 2nd set. They should be in demand once collectors start thinking about how beautiful the coins are in the pre-1982 metallic composition. I'm pretty sure the proof cents are the same, but not everyone likes proofs, though I like them, too, and will eventually get them as well. You might want to get a mint set, too, while the price is still low.
