500 Euros Palace of Versailles

Issued as part of Monnaie de Paris's ongoing "Monuments de France" program, this coin was struck the same year UNESCO added the Palace and its gardens to a joint management plan aimed at addressing chronic subsidence damage to the Hall of Mirrors ceiling — repairs that had been debated and deferred for over a decade. The 155.5g specification places it in the five-troy-ounce category favored for high-denomination collector bullion, a format Monnaie de Paris had been refining since the early 2000s.

Mintage for this issue was capped at 99 pieces.
