The mintage of the 1921-D is the lowest of the entire Walking Liberty Half Dollar Series at just 208,000. It is the most valuable Walker in circulated grades trailing only the 1919-S and 1921-S in Mint State. It is still very rare in uncirculated grades up to MS66 at which point it is an extreme rarity. Solid strikes, nice luster and varying levels of toning can be found with a closer look.
