1891 and 1892 were transitional years with different fonts used, different Obverses & different Reverses. The coin pictured in the thread is a corroded 1891 Obv 2 Large Leaves(LL), Large Date(LD)
You can tell those with Large Leaves(LL) by looking to see if the leaves touch the denticles at the 6:30 or 8:00 postion (leaves 9 & 11, numbered from 12:00). If they do, it's a large leaf. Small leaves there is a good gap between the leaves and the denticles. You can tell the large date from the small date by normally looking at the 9 in the date. The large date had a large 9 that has an almost round center to the loop of the 9. Also a vertical line drawn down the outside of the left leg of the N in Cent will always touch or intersect a Large Date 9.
