Monnaie 20 - Monopoly

Monopoly play money has gone through several redesign cycles since Parker Brothers standardized the pastel color-coding system in the mid-twentieth century. The 2001 Hasbro edition introduced a watermark into the paper stock — an unusual security measure for a game component, likely driven by concerns over counterfeit play money being used in retail fraud schemes, a documented problem in the late 1990s when color inkjet printers became household items.

The watermark is the only catalogable feature of genuine collector interest here.
