1776-1976 Quarter Double Die Obverse Error (FS-101)

The 1776 to 1976 Quarter FS-101 Double Die Obverse represents the most sought-after error in the bicentennial series, showing clear doubling on "LIBERTY" and "1776-1976," particularly visible on the letter "R" in "LIBERTY." Examine the "R" under magnification for distinct doubling on the left stem. High-grade examples have sold for thousands of dollars, with this error easily visible to the naked eye once identified, making it excellent for cherry-picking from circulation.

1776-1976 Quarter Double Die Obverse Error (FS-102)

The FS-102 variety displays pronounced doubling on "IN GOD WE TRUST" and Washington's profile details rather than on "LIBERTY." This scarcer variety lacks the clear doubled "R" that characterizes FS-101. Inspect "IN GOD WE TRUST" and Washington's hair for spreading effects. Values for high-grade FS-102 examples exceed those of FS-101 due to greater rarity.
