Halve daalder, noodmunt uit Groningen, geslagen tijdens het beleg (voorzien van het portret van Karl Rabenhaupt) 1672

This silver coin, or "noodmunt," was created in 1672 during the Siege of Groningen. The coin is a diamond shape and features the portrait of Karl Rabenhaupt, a German general who led the siege. This was a desperate measure taken by the city of Groningen to pay its soldiers during the siege. The reverse features a coat of arms. This coin, a rare example of numismatic art, is now housed in the Rijksmuseum.
