This is an extremely rare pair of German 3 Mark Mint Errors. One is a deep reverse die cap shaped like a bottle cap. The other was struck 40% off-center and is shaped like a baseball cap.

Both are in gem mint state condition and both are superb examples of a deep die cap and an off-center strike. Major off-center strikes and die caps on German 3 Marks are extremely rare.

Die Caps & Off-Center Strikes are featured
in my NLG Award winning book,
World's Greatest Mint Errors.
