1922 Philadelphia & Denver Peace Silver Dollar Pair, Very Fine. These big 90% silver coins were the hard-asset backbone of America, in the days when a dollar was a dollar. The first high-relief 1921 issue had created stacking problems at banks. This second year 1922 Philadelphia Peace silver dollar introduced the modified-relief engravings that became the standard for Americas last circulating silver dollar series. The Denver Mint began striking Peace dollars in 1922. This first D-mint Peace dollar had a mintage 25% less than the final Morgans that were struck there the previous year. Today, fewer than 1% of its output survives in mint-state quality, putting added pressure on circulated issues like these Very Fine quality specimens.
