The 1973-D Lincoln Cent is really common in circulated grades all the way up to MS64 condition. In MS65, examples are difficut to find but can still be found in rolls, bags or in mint sets. Examples in MS66 are scarce as most have nicks, scratches or carbon spots. In MS67 condition they are really scarce and hard to find. Most of them have probably already been pulled from mint sets or rolls. There are less than two dozen known in MS67 or higher and one of the tougher issues from the memorial cent series.
