There are quite a few Double Die Obverse Varieties for the 1970-S "Business or Circulation Strike" Lincoln Cent, most of which carry a little premium except for the DDO-001 which can fetch prices approaching $1,000 in EF-45 alone and the values go up significantly for Uncirculated Red specimens. There are also the "Small Date" and "Large Date" Varities and quite a few RPM (Re-Punched Mint Mark) Varieties. The Proofs even have quite a few of all of these and some of the DDO's carry significant premiums. I used to collect some of the Proof DDO's, which I found on Proof Cents that I had purchased and once had some of finest known.
