1820 “STATESOF” Capped Bust Dime
The 1820 “STATESOF” Capped Bust Dime is one of the most appealing varieties in the series. The variety is quickly identified by the placement of the words “States of America” in relation to each other.
The words of the inscription were improperly placed by the die maker, crowding together the three words of the inscription. The reverse die was first used to strike a reasonable number of dimes in 1814, after which the die was placed into storage. No dimes were produced for several years, but when production was resumed in 1820, the reverse die was used again to strike the scarce die marriage known as JR-1.
This is one of several Capped Bust Dime varieties listed in the Red Book, and its unusual nature leads to popularity with collectors. Most coins available are circulated, although uncirculated examples appear on the market every few years.
1829 “Curl Base 2″ Capped Bust Dime
Identified as JR-10, the 1829 “Curl Base 2″ Capped Bust Dime is the only variety of the year with a curled base 2 in the date (pictured at left above), as opposed to a square base 2 as all the other varieties (pictured at right).
Ranked as a R-6, there are only an estimated 30 pieces known to exist across all grade levels. Interestingly, this variety was only discovered in 1973, and virtually all known examples are in extremely low grades. Many examples will also exhibit damage or cleaning. This variety virtually unobtainable in grades higher than F-12.
While there are a few more rare die varieties within this series, the 1829 JR-10 is the penultimate variety, and the true key set to a full set of Capped Bust Dime die varieties. Examples graded Good-4 have recently sold for prices in excess of $5,000 at auction.
