U.S. Mint coin reference
Liberty Seated quarters ran for decades and include multiple subtypes.

Obverse: Liberty seated on a rock holding shield and pole.
1866–1891: Liberty Seated Quarter (Variety 3: "In God We Trust" Motto Added) adds IN GOD WE TRUST above the eagle in 1866. The subtype begins on the reduced 6.22-gram standard and later includes the 1873 adjustment to 6.25 grams.
Arrows beside the date identify the 1873–1874 weight change. Coins after the arrows were removed keep the 6.25-gram standard, so date and marker details control attribution.
