I hope this question makes sense.
I have a 1921
Peace dollar with what appears to have unique
Machine Doubling errors. Already posted here:

Question:
When, if ever, does the same error found on multiple coins, become a unique variety, such as a newly found
VAM? Or... is it just a continuing MD on multiple strikes?
