5 Mark - Kirschau Vereinigte Spinnereien u. Webereien G.M.B.H.

One interesting fact about this coin is that it was made of aluminum, which was a relatively new material for coins at the time. Aluminum was first used in coinage in the late 19th century, and it was not widely used until the early 20th century. The use of aluminum in coins was seen as a way to reduce the cost of production, as it was less expensive than traditional metals like gold, silver, and copper. The 5 Mark coin from Kirschau is a rare example of a coin made of aluminum, and it is a unique piece of numismatic history.
