I was examining my "junk silver" and noticed a 1928-S
Standing Liberty quarter. According to my 2021
Red Book, there are large and small varieties of the 'S' mint mark. I'm certain that this is a large S. Aside from the mention in the
Red Book that large and small varieties exist, I cannot find anything regarding the number of large vs. small mint marks, or the value of large vs. small mint marks.
Does anyone have any ideas on where I can find this information?
Thanks for any help you can provide.
