The 1921 Philadelphia Mint Walkers come from a very low relative mintage of just 246,000. Only the Denver Mint issue of this date had a lower mintage. The 1921 is very scarce in circulated grades, very rare in Mint State and not a gem rarity like its counterpart minted in San Francisco that same year. It is known for a very strong strike, with many having nice luster and toning.
