B1 Reverse (Long Nock, Parallel Arrow Feather) B2 Reverse (Short Nock, Parallel Arrow Feather) I'm attributing an 1878 7TF Reverse of '78 Morgan dollar. This coin has a Long Nock over a Short Nock. Note that is not a choice on VAMWorld. Question: Why isn't there a B3 Reverse (Long Nock/Short Nock)??? It would save me a lot of time .
For obvious reasons, I am sure you cannot, but photos of the coin in question would help. I'm not a VAMmer and I am not questioning your abilities. But, even NGC and PCGS can attribute some VAMs as different reverse varieties. I would suggest that there is possibly not a B3 reverse because one does not exist. It may be possible that you are looking at a B/A reverse variety. Or, maybe you have discovered a new reverse variety. Maybe you'll find your coin similar to one of these.
What you have shown is exactly what I'm writing about. There is an extra little nock at the end of the bigger one. Also note that these are described as a long nock variety. The other 7 TF long nocks have a solid long shaft that is completely different.
The 7/8 tailfeather were made using the short nock reverse and was continued to be used until the new long nock reverse was made available, in the interim the "extra" piece was added by hand. Here is a thread that discussed such an issue https://forums.collectors.com/discu...ed-on-1878-morgan-dollar-7-8-tf-and-7-tf-hubs
A picture would help, but it sounds like one of the "7/0" B/A (7/8 TF) reverses. If it were a B2/B1, it would be cataloged as such, and not as a B3, since it's not a distinct hub. It appears that the B2 reverse may be the result of a broken hub. The 1878-CC VAM 13 shows what is likely the remnant of the hub break. The dies are hubbed 7-10 times to bring the design up, and a hub break between hubbings could manifest itself as what is seen on that coin.
Agree, B2/B1 would be a nice addition. I posted B3 out of ignorance. 7/0 is what the submitter thought but it did not match any 7/0 VAMS. I'll see if it is still around.
