A local newspaper operating in the South-East of the Netherlands, Limburger Koerier, seems to have found the idea of a metallic ad attractive. It issued an advertising medal of the same size (about the size of a silver 1 gulden) and metal (aluminium). It is also dated 1931, but the circulation figure is significantly higher, at 50 000. Yet, they promote small ads for 60 cents. I think this was the smarter strategy. Anyone may feel like placing a small ad but large ads are sold to companies, a much smaller target for a token that seems best suited for liberal distribution.
The above token came from a dealer. The token below was a gift from a metal detector pilot.
