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

This 17th-century silver coin, created during the Siege of Groningen in 1672, is a rare example of Dutch numismatics. It features a portrait of Karl Rabenhaupt, a German general who led the siege, on one side and the coat of arms of Groningen on the other. This small but significant artifact serves as a reminder of a crucial moment in Dutch history and is currently housed in the Rijksmuseum.
