3 Pfennigs / Kipper Dreier - Georg Wilhelm Sorau

Sorau's 1622 Dreier is a product of the Kipper- und Wipperzeit, the currency crisis that swept the Holy Roman Empire between roughly 1619 and 1623, during which mints — municipal, princely, and episcopal alike — debased silver coinage on an industrial scale to profit from arbitrage before the system collapsed. The City of Sorau, a small Lusatian town under Hohenzollern administration, was among hundreds of minor issuing authorities that briefly operated emergency mints during this window.

At 0.45 g, this piece contains almost no silver worth recovering, which is precisely why so many survived unclipped.
