Krause lists two types of 1881 English penny: 1881 Fine $10 1881 Obverse as 1880, shield heraldically colored, Fine $100. There's no illustration, and I don't have the slightest idea what this means. My 1881 has a design on the shield, but I don't know if it's the normal shield, or a "heraldic" shield. Can someone tell me which variety I have? The image has been lightened quite a bit to make the shield show clearly.
The diagonal cross is split down the middle instead of having 2 skinny borders like the main vertical cross (St. George's cross). Yours is regular, sorry.
