I am working on learning to plate 1851-56 3c Washington Stamps. I've picked some distinctive ones that might be easier to plate, but I'm having trouble right away. This one looks like a B Relief to me (maybe a C with very faint shoulder gash), and it has a guide dot in the UR. It also has some distinctive recutting along to top frame line and a possible double impression (seen in center of the UL rosette. I think it is from plate 1L, 2L, 3, or 5L.
I checked all the stamps with a guide dot in the upper right (regardless of plate or relief), and I must have missed this one - I was trying to match on the top frame line recuts.
Can anyone help? I'm more looking for help on the process of plating than the actual position, but ultimately, I want to know what position this is too.
