200 Dollars - Elizabeth II Treasure

The "Treasure" release belongs to the RCM's ongoing fine gold bullion-collector hybrid program, where selective electroplating with rose gold alloy is applied over the .9999 substrate after striking — a post-mint process that distinguishes these pieces from conventional two-tone dies. The rose gold accent work is decorative finishing, not a second alloy poured at the planchet stage, a distinction that matters for anyone assessing the coin's metallurgical integrity.
