Yep, S-249 the corrected fraction. This reverse die is actually a leftover die from 1801. In 1801 they accidentally made five different reverse dies with 1/000. All five were used in 1801 with one of them having first been corrected by cutting a 1 over the first 0. One of the 1/000 reverses was reused in 1802 on S-228, and one of them (1801 rev K not J as stated in Breen's book on cents.) was corrected in 1803 and re-used to strike S-249. (It is not the same die as the one corrected in 1801.)
