Strafgevangenis Ommerschans, huismunt geslagen op last van de Maatschappij van Weldadigheid ter waarde van ½ cent before 1830

This is a half-cent coin made in the Strafgevangenis Ommerschans prison before 1830, as a form of internal currency. The prison was part of the Maatschappij van Weldadigheid, a Dutch philanthropic organization focused on penal reform. The coin, a circular metal disc, bears the inscription "1/2 C" on both sides, symbolizing its monetary value. This coin, now part of the Rijksmuseum collection, is a tangible reminder of the prison's history and the unique social and economic conditions of the 19th century.
