I think you need to provide a scan at 600 dpi or better. When I copy your jpeg I can clearly see the "9" but I cannot discern the number to the right. Here is a jpeg of plate #150 I just scanned at 600 dpi - that said - the imprints can ve lightly struck, obliterated by cancels,etc so that some cannot be 100 per cent assured.
The letters have nothing to do with the plate number.
The bottom letters reflect the position in the sheet. In your example, it is position JC
(10th row, 3rd from left) in a sheet of 240 stamps (20 rows, 12 across). The top letters are simply the bottom letters reversed.
Yours looks like plate 97 to me:

Here is the last question I have about those 1890 era stamps I acquired last week. If I tell you that the UL letter is G, the UR letter is C, the LL letter might be a I, and the LR letter is a C, can anyone tell me the Plate Number? I can't read it in the scroll work, even with a powerful magnifying glass. Thank you.
