20 Cents Pattern

France's 20-centime denomination had effectively ceased to function in commerce well before 1928, making this pattern's purpose somewhat ambiguous — it may reflect exploratory work tied to postwar monetary rationalization rather than any serious reissue proposal. The Monnaie de Paris struck occasional brass trials during this period as cheap substitutes for silver blanks when testing new or revised dies, which likely explains the composition here rather than any intent to circulate brass as currency.

The Lecompte reference notes this as a brass variant, distinguishing it from better-documented cupronickel and aluminum trials of the same type.
