I am too green at currency to catch what you're throwing down. Do you mean they are the first ever print of each note or... ? Sorry and thank you for helping me learn.
They're the first designs. I know the $1 one is for sure. I think the $2 one is too. Then of course the designs changed through the years.
I'd think so. I certainly wouldn't let them go at face value. For the fair market value you'd have to research it. These we don't have off the top of our head. Just knowing they're the first series prints or designs I'd think you'd want to tack on something just for that. From there, the grade would be determinative. Just put in the effort and estimate off comparable grades. Grades are condition, that's all. Like a baseball card or comic book, the newer and less-damaged, the better, translated, more valuable.
My opinion, as far as value: The small size notes are all spenders, especially the $20 and $10. Given the condition, the $1 silvers are not worth enough above face to be worth trying to sell. I don't think they are rare varieties. Star notes are always nicer but that has a piece missing and stains. The large notes are obviously not spenders, but I don't think they are especially valuable, and not in the best condition. But those are nice enough to save for sure. My opinion, as far as collecting: Keep whatever YOU think is interesting.
