To give you an example of what I'm talking about; there's an antique 1800s MOP French jeton w/ only an engraved pig... Found out years later the place had the best rib joint in town...

Seriously -- Here are examples of the Forges-les-Eaux I mentioned above: The center blue only had "100" on the reverse... but of course to everyone in that area they knew what the obverse was. Then, a few years later I found the other more-recent jetons w/ the name on the other side.
