1882 CC LFC VAM3 thru 3D
John Austin is correct, Coin 3 is the stage of VAM 3 that exists between VAMs 3A and 3B. Coins 1 and 2 are correct, and Coin 4 is a VAM 3A, but it is before Coin 3 in the progression. Coins 6 and 7 are virtually identical in stage, but lighting hiding some of the similarities. They are both examples of VAM 3D. VAMs 3B and 3C are both somewhat elusive, but neither is truly rare. VAM 3B has the strong clashing at the neck as pictured on its page, but little or no cracking above the cap. VAM 3C has the same clashing as VAM 3B and clearly visible cracking with some displacement around the cap. The quick and dirty difference between 3C and 3D is that the 3B clashing has not been polished down on the 3C part of the progression.
Lots of stages in this progression and many of them are minor. I'd question the attribution of anything called 3D that still has the 3B clashing intact. Additionally, I'd question anything called 3C that doesn't have the polished down clashmarks. The cracks begin to form during the 3B stage and are almost fully outlined before this polish job took place. The displacement gets stronger after the present stage as Russ noted, but this makes for a clear 'black and white' stage transition instead of the grey area in much of this progression. As I explained at FUN, this is the earliest version of what should be called VAM 3D, regardless of what the listing says.
