Even though the Indian Quarter Eagle represented a dramatic departure from traditional coin design, the planchets used to strike the coins remained the same. The composition was 90% gold and 10% copper with a weight of 4.18 grams and diameter of 18 mm. All coins have a reeded edge.
The edge of the coin is reeded, but unlike the previous coins of the United States the rim is not raised. Due to this unique configuration, most coins exhibit multiple marks from handling, making a gem set a major challenge.
The mint mark for the three Denver Mint issues is located on the reverse of the coin to the left of the arrows. Philadelphia minted coins to not carry mint marks. It is notable that the mint marks are raised on the coin, while the rest of the design is incuse.
