10 Pesos 'The Liberty', Piedfort

Piedforts — coins struck at double or triple the normal planchet thickness — have been a deliberate collector vehicle since the French Monnaie de Paris formalized the format in the 1970s, and Cuba adopted the practice enthusiastically during the late 1980s as a hard-currency earner. With the Soviet subsidy apparatus beginning to fracture, the Cuban state mint leaned heavily on numismatic exports to generate convertible foreign exchange — piedforts commanded premium prices in European and Latin American collector markets precisely because their inflated silver content made the markup easier to justify.
