Nearly identical in design to the Bust Half Dimes, the Capped Bust Dime was designed by John Reich. Issued between 1809 and 1837, all Capped Bust Dimes were struck at the Philadelphia Mint. Over eleven million coins of this design were produced with only two dates, the 1809 and 1811/9, having mintages of less than 100,000.
- 1809-1827 Capped Bust, Open Collar Type
- 1828-1837 Capped Bust, Reduced Design
While many letter, date, and overdate varieties were produced, the important feature of this series was a change in the diameter of the coin in 1828. The addition of new Mint machinery in that year allowed all subsequent Capped Bust Dimes to be struck with a uniform diameter of 17.9 mm. as opposed to an approximate diameter of 18.8 mm for all previous dime issues. This new machinery also allowed the use of evenly beaded borders, which replaced the oftentimes-uneven serrated borders used on earlier issues.
