Liberty Seated Double Dimes - Die Marriage Set

The Double Dime (or twenty-cent piece) was the shortest denomination struck for circulation in U.S. History. Easily confused for a Liberty Seated Quarter, the Double Dime was only issued for commerce in 1875 and 1876. After the coin was dropped for circulation issue, it was struck in proof format in 1877 and 1878 for collectors. Normally collected as a type coin (usually 1875-S), there are several ways a collector may pursue the series.

A Die Marriage set consists of 29 issues, representing all known die combinations for the entire series, excluding the 1876-CC. This will take years of search, but is quite managable, as most of the die marriages are for the common 1875-S, the cost will be managable, and is perhaps the fewest die marriages for any Liberty Seated series. But it will be a challenge, as there are some rare die marriages mixed in. Still, there are a number of rare die marriages ready to be cherrypicked, as there are still few people actually looking for them. Attributions can be performed by using the book Double Dimes - The United States Twenty-cent Piece (with two Addenda) or the web book of the same at www.doubledimes.com.

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 John Frost.
