Raymodj, I'm sure Winston, Art or Ray.Mac can expand on this--- but I think when it was discovered that the design of the one-cent Franklin was too big for the plate, a portion of the design needed to be burnished (erased) out and that's what caused all the design differences creating all the different listings for the Franklin. Only #5, which is one position on on plate #1 wasn't burnised.
The difference in the V and Va is in the amount of erasure done to the left side on some positions on plate 5; most if not all of the right pane and some of the left pane. I don't know if its know why some were erased more than others.
This may not explain what you want to know--as I said there are at least those three mentioned above that know a lot more than me about this issue.
I'd think that the experts would be lobbying Scott for at least a sub-listing for the Va. The difference between a 6 and 6b isn't anymore significant to me.
