Post WW1 German Workers Medallion 1925.

Post war Germany was almost in chaos, with hyperinflation, unemployment and lack of basic necessities caused various uprisings around the country. I do not know why this white metal medallion was minted but it is pro worker, probably by the communist or another political party at the time; around the obverse is written, roughly, 'The work is the rock on which the Riech will benefit'. It also lists the cost of everyday goods, such as 1lb meat 3200 Milld, Bread 840 Milliard, Potato 5000 Milld, and so on. May be these were just given out in the street to passers by to gain support for the party, what ever it was I can not find another one. It is in very good condition and measures 1.5 inches in diameter. An interesting piece of German social history after the great war.
