As with the 1823 Dimes, all 1824 Dimes are overdated from old, unused 1822 dies. Mint employees utilized one obverse die and two different reverse dies to strike all of the 1824 Dimes. On the more common JR-1 reverse, the 1 of 10C has a flat top and a missing serif at bottom right. The more rare JR-2 variety has a curved top and perfect serifs on the 1.
Mint State 1824 Dimes are very scarce, but they often come nice. Fully struck examples are very rare, though they do exist. The best examples top out at MS66.
