Prussia 1871-A 20 mark
"Preussen, Königreich, Wilhelm I. 1861-1888. 20 Mark 1871 A, Berlin. Fast vorzüglich. (kingdom of Prussia, William I, 1861-88, twenty mark of 1871, Berlin mint. About extremely fine.)"This type was struck 1871-73 in substantial numbers from the Berlin (mintmark "A"), Hanover (mintmark "B") and Frankfurt (mintmark "C") mints during the reign of William I, emperor of Germany 1871-88. It was superseded in 1874 by a revised reverse. Tho this later type was struck 1874-88, it is not as common as the type shown here. There is a concurrent ten mark gold piece (Fr-3819) with a similar design. After the unification of Germany in 1871, the previously independent states were permitted to mint coins of a face value of two mark and up while the smaller coinage was struck to a uniform design.
