10 Dollars Barbara Bush, Bullion Coinage

Barbara Bush appears here as part of the American Women's quarters-adjacent bullion program, but this is the half-ounce denomination in the First Spouse Gold series — a program that has quietly run since 2007, striking .9999 fine gold coins honoring each president's spouse in order of administration. Bush's coin was released in 2020, the year mintage figures across the series collapsed to some of the lowest on record, with many issues falling below 1,000 pieces struck across proof and uncirculated formats combined.

Low mintages are structural here, not accidental — the $10 face value bears no relationship to gold spot, and the coins were never priced for casual buyers.
