CUBA. Banco Nacional de Cuba. 20 Pesos, 1961. P-97x. USA C.I.A. COUNTERFEIT. PMG Gem Uncirculated 66 EPQ.A very historical item from the Bay of Pigs Invasion of Cuba. These counterfeits were produced by the C.I.A. and show prefixes F69 or F70, often without serial number (as seen here). It is reported that each member of the invasion force carried a pack of these with them. The exact purpose of these is unclear although it was probably done to undermine the Cuban economy through bribes and the like. Of great historical significance and a storied relic from a turbulent time in world history.
