Capped Bust Half Dimes - Ultimate Set

A set of Capped Bust Half Dimes complete by variety (the Ultimate set) is no easy task with 123 coins including a R8 and 6 R7s. The pursuit of the ultimate set collection requires patience and persistence, but also provides for those who love the thrill of the hunt - these little beauties grow on you quite quickly. Almost more difficult than finding a selection of these coins is finding the reference book used to attribute them Federal Half Dimes 1792-1837 by Russell J. Logan and John W. McCloskey published in 1998 by the John Reich Collectors Society. Liberty Seated Collectors would recognize John's name - the current President. Their 293 page book is considered the Bible among collectors and dealers alike. While not in color, it gives a very pleasing picture of every variety obverse and reverse. The book covers early half dimes too, but this is beyond the scope of Capped Bust Half Dimes. The authors describe Emission Order, Remarriage charts and die deterioration and provide a cross reference from Valentine's numbers. Their quick finding chart is very helpful in determining the correct number for any date. Like any good reference on coins, the authors have their own 'code' to describe what they reference within the text of their descriptions.

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 Okerson.
