I noticed this too many times now to not say something about it…..your thought plz….backwards letters, numbers used as letters and vice versa
It's tough to see what you're seeing without some extra sharp photos...but I am seeing coins with wear and damage and maybe possibly a small die chip here and there. Pick one of those or give us information about what you think you're seeing and where on each one... The photos are ok, but not sharp enough to make determinations about things.
Your photos could be better, considering whatever it is you are asking us to see. It really helps if you say what you think the relevant feature is.
If you look At the die making process, you'll understand that letters and numbers aren't punched into individual dies. The mint starts with a master hub. It has all of lettering in place. In the past, the master hub would be used for years, but now they make a new one each year. Master dies are made from the master hub. Working hubs are made from a master die. Working dies (which strike the coins) are made from a working hub. The only place that a letter or number can be changed is on the Master Hub, and if that happens, then EVERY working die, and therefore, EVERY coin would have it. You're just seeing circulation damage Here is a good link explaining the die making process. https://www.doubleddie.com/58201.html
