Hey! Ima gonna be nisa to youa cuz it's yo first post. The pictures should be from a cellphone a least. What you are seeing is Machine doubling or sometimes called Strike doubling OR "Worthless Doubling". Welcome to the forum pal!
Either is machine doubling or a minor DDO. There are no well-known DDOs for a 1919-S, but this could be one.
Likely may not exist if Variety Vista hasn't caught it, but there is a small chance it can. Seems that VV us quite good, that's where I attributed the one 1964 penny I cared to put aside for no reason and later found it to be a DDO from die 22.
I'm not sure how they find what die was used; however, that has a significant role in more major DDOs, such as the 1972. FS-101 is one of the most popular, FS-104 is by far the rarest, and others don't go for as much. All the FS's are from different dies, if I remember right.
Looks flat and shelf like to me and that means MD or mechanical doubling. Not the type of doubling you want. Welcome to CT.
Do you have a source for that? Are you sure you're not confusing a Variety Vista DDO number with an actual die number used by the mint? http://www.varietyvista.com/01b LC Doubled Dies Vol 2/1964PDDO022.htm is the 1964 DDO-022 listing. 022 isn't a "die number", it's just the number they assigned to the DDO. Otherwise I have a difficult time understanding how anybody would know which die number was assigned to a die that produced a variety, unless someone went back through all the dies and matched one up to the particular DDO. With a mintage of 2,648,575,000 you would have to pick that specific die out of about 3000 others. I suppose the mint may have discovered the problem during QC, knew which die it was, documented it, and let those coins enter circulation anyway, but I've never seen mint records go into that level of detail. They would have to be. The only exception I can think of is if two different FS designations are later determined to be the same variety.
