Don't take this the wrong way. I researched the issue which is what you should do and if you find no answer, ask us and we will be happy to help. Ps. 1950's coins can cause headaches because of the subtle differences between varieties. Now I'm going to take a couple of aspirins.
Haha no offense taken. I promise I am doing research on the coins before I post, I just don't always understand what I'm reading/researching evidently. Having it broken down like you did made it much easier for me to understand and apply. Being new to coin collecting/identification is rugged, there is so many subtle things to learn.
And then you have something you can’t see except through high-magnification that’s not worth nothing to nobody or if you have something against the use of double negatives anything to anybody.
