1 Pfennig

Rietberg was a small County in Westphalia, and its local copper pfennig issues of the 1630s exist precisely because the Thirty Years' War had catastrophically disrupted the supply of reliable small change across the German states. Municipal and territorial authorities struck emergency copper pieces to fill the void left by hoarded silver and the collapse of normal mintage infrastructure. Rietberg's issues from this period are genuine small-denomination necessities, not prestige coinage.

The County changed hands through inheritance disputes repeatedly across the seventeenth century, complicating attribution of specific issues to particular counts.
