Liberty Seated Quarters - Carson City Dates

There were only eight years in which Liberty Seated Quarters were produced at the Carson City mint, 1870 to 1873 and 1875 to 1978. The four earliest issues are frequently referred to by collectors of the series as "the big four CC's". Their extreme rarity and associated cost have given pause to many set builders. Although the 1876 to 1878 issues are readily available, the 1875-CC quarter has become very popular and very scarce in recent years.

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 or variety is based on availability in grades of EF-AU and uses a scale of R-1 through R-8 with a R-1 weight being the most common while a R-8 weight being the most difficult to locate. Rarity estimates are from Greg Johnson with the Larry Briggs Liberty Seated Quarter book as reference.
