Germany 1951G 2 Mark, Unauthorized Restrike, AU-50 - One year only, scarce mint mark

Germany 1951G 2 Mark, Unauthorized Restrike, Almost Uncirculated (AU-50). Copper-nickel. This denomination was only issued in 1951, owing to the ease of confusing it with the 1 Deutsche mark. G, for the Karlsruhe mint facility, is the least common of the four mint marks. Even more intriguing, someone at the mint restruck some quantity of 1951G 2 marks without sanction.
