Normally, the 1820 JR-2 Dime would be a regular old, somewhat scarce, die variety. However, because of some heavy and obvious recutting on the reverse, this variety has become known as the "Office Boy" reverse, presumably because only a low-level person could have made such amateurish mistakes. Walter Breen described thsi reverse best in his 1988 Encyclopedia: "...part of another letter between D S; MS join at tops and feet; many letters repunched and irregularly spaced."
This variety sometimes comes with streaky planchets cause by impurities in the metal alloy that stretched out as the raw ingots were pulled through a drawing bench to form the strips from which the blanks were punched.
Approximately a dozen Mint State 1820 JR-2 Dimes are known. The best examples include a pair of PCGS MS67 examples, one of which sold for a record price of $152,750 in 2014.
