2 Francs - Rainier III Gold Piedfort

Piéforts are a French minting tradition dating to at least the 13th century, originally produced as official weight references and presentation pieces for the issuing authority. Monaco's modern gold piéforts of this period were struck by the Paris Mint under the technical and administrative relationship that has governed Monegasque coinage since the 19th century — the Principality issues its own coins but relies entirely on French minting infrastructure.

The 1982 date places this within the final decade of Rainier III's reign, by which point Monaco's collector issues had become a significant revenue stream, with piéforts produced in strictly limited quantities for the philatelic and numismatic market rather than any circulation purpose.
