In accordance with the Coinage Act of 1792, the earliest quarter eagles were struck from a composition of .9167 gold and .0833 silver and copper. Planchets vary in diameter, but most will be close to 20 millimeter. To prevent clipping, all have a reeded edge.
Uncirculated examples will weigh 4.37 grams (67.44 grains). As with all early American coins, striking quality varies, but most will be at least somewhat lightly struck near the centers. Fully struck pieces are virtually unheard of, and any piece which displays an exceptional strike will command a premium from specialists.
Like other gold and silver denominations, adjustment marks are frequently found on this type, but these will not affect the grade, as they are Mint made.
