Congrats on the pickups! The spots on a few of them bother me. The 53 Vicky is especially troublesome, and exhibits many green spots that appear to be active corrosion/PVC/green-death. That 1806, however, is very attractive! (I would grade it high AU, by the way: it appears to have some rub, and the Brits are far more conservative with grading).
The 1854 also has some spots that need be watched . I got so carried away with the dates the PVC damage I must admit wasn't even noticed.
