$2.5 Quarter Eagle, Indian

The Indian Head design was used from 1908-1929 and was designed by Bela Lyon Pratt. The design featuring a sunken motif of the Indian head on the obverse and an standing eagle on the reverse is a popular series. The $5 coin of the same period used the same design. Popular with collectors, the set can be completed in almost uncirculated condition and even in low mint state without difficulty. Assembling a set in gem mint state is a challenge.

Rating: The weighted average of all coin grades (i.e. aggregated sum of each coin grade + CAC premium multiplied by its rarity factor divided by the sum of all rarity factors). Missing coins are included and assigned a grade of 0. This metric is the basis for order rank.

Complete: The number of coin entries divided by the total number of coins in the Set.

Weighted Grade: The weighted average of all coin grades (see calculation above), but excluding any missing coins.

%: The ratio of coins certified by CAC (either green or gold sticker). Calculated as the number of CAC coins divided by the total number of entered coins.

Rarity Factor: The rarity assessment for each date/variety uses the Sheldon scale of R1 through R8 with a R1 weight being the most common while an R8 weight being the most difficult to locate. Rarity estimates are by Osprey.
