As far as I know, there are no other varieties for QEII. There are, however, varieties for KGV and KEVIII. There are two varieties for George. The first, Obverse 1 has the "TT" in "BRITT" on the obverse close together. Obverse 2 has them, obviously, wider apart. The Edward ones are the 1902 specimens which are identified by the quality of the striking. Type A, the one commonly held to be first minted, has a weakly struck area on the breastplate of Britannia on the reverse, with little or no detail. These only crop up in the higher grades however. Type B is the common issue. And of course there are the different tides on KEVII: Low Tide : 1903 High Tide : 1902, 1904-10
