500 Dollars - Elizabeth II Christopher Columbus

Issued as part of the broader wave of Columbus quincentenary commemoratives that flooded the market ahead of 1992, this BVI piece is notably struck in .500 fine gold — an unusual fineness chosen almost certainly to hit a lower price point while maintaining the optics of a gold issue. The 19.81g weight at half fineness yields roughly 10g of actual gold content, a figure that mattered considerably when bullion hovered around $360/oz in 1991.

The quincentenary market was badly oversaturated. Dozens of issuing authorities produced Columbus gold across 1991–92, and secondary market premiums on most collapsed within years of issue.
