The 1930-D Lincoln cent is not generally considered a semi-key coin, but in the Mint State grades it nevertheless is one of the toughest branch-mint issues from the series with a 1930s date. In MS66 and above this coin numbers fewer than perhaps 200 specimens, and in MS67 the coin is downright rare. Of course, this inspires fervent bidding from registry set collectors for an example in that elusive grade range, and therefore anyone wishing to buy MS67 examples of the 1930-D Lincoln cent should be prepared to pay strong premiums.
