5 Pesos Boxing

Cuba's late-revolutionary commemorative program of the late 1970s and early 1980s produced a dense run of silver issues targeting the collector export market — hard currency the government badly needed as the U.S. embargo tightened economic options. The boxing subject was no accident: Cuban amateur boxing had become a source of genuine national prestige, with Teófilo Stevenson's consecutive Olympic heavyweight golds in 1972 and 1976 elevating the sport to something close to official ideology.

The dual KM and JMA references suggest this type circulated through multiple specialist catalogs, a common feature of Cuban issues where collector distribution was handled through state export channels rather than conventional numismatic trade.
