1876 Germany 1 Mark Obverse Indented by a 20 Pfennig Planchet
NGC MS 63 UNIQUE
$5,000
This unique 1876 German silver 1 Mark was indented by a 20 Pfennig planchet with a diameter of 16 mm. It was authenticated and certified MS 63 by NGC. I cannot recall any other pre-1900 German coin that was indented by a smaller planchet.
U.S. and world coins that have been indented by smaller denomination planchets are very scarce. This is especially true on older type coins. A great example of this is an 1860 New Orleans Seated Half Dollar that was indented by a Half Dime planchet. It is part of a mated pair with the other coin being a Half Dollar struck on a Half Dime planchet. Both were certified by PCGS as a mated pair.
It is possible that the mate to this unique German mint error, an 1876 1 Mark struck on a 20 Pfennig planchet, was also accidentally released by the mint and if ever found, would create a spectacular mated pair, just like the Seated Half Dollar and Half Dime.
Here is a rendering of what the missing mate to this indent would look like:
