The lowest value jetons I know of were from France
(0.05f), about 7¢. I have about 25-pieces going
back to early-1961 available to the first 25 people sending a
S.A.S.E. These are actual 0.50 N.F. (New Franc)
casino jetons (not counterstamped) made when France
introduced the Monetary Reform Act where every
100f became 1-New franc (NF).
