Sew... W mint marks are too easy to find, so I'm putting those on hiatus. I mean, I've already found 7 this week, 4 from 2019, which i found doubles of War in the Pacific on the same day. Too easy. I figure S mint marks must be much harder to find. Nope. And as you can see, this is the "light s" variety, where they didn't use enough ink when striking. Very very rare.
Oh yeah. This guy too. No mint mark, but rare none the less. As you can see, this is the one with this reverse on it. Very very rare.
This is another one i found, just using it as an example of an S that was struck with enough ink. See? Perfect amount of ink. The person running the coin inking machine that day, really knew what they were doing.
I'm not back. Today i found 8 keeper quarters. A very good day. I really thought finding S mint marks might create a challenge, sigh. S first.
