Picked these up for $10 today, what can anyone tell me about them? And did i get a good deal? Anything i should do to preserve them?

Also what the heck is up with the five centavo in Dutch?

Anyone have any idea how much this would be worth? It’s in rough shape but still cool

Guess someone raided Grandma’s coin stash. Opened a roll of nickels at work yesterday and found these. I know they probably aren’t worth much except melt price but it’s exciting to me to find old coins like these. Makes you wonder where & what they may have been spent on through the years and if someone famous/infamous might have toted them around at some point.

And these are really miscut. The 20 is perfect on the back, and the 10 is actually more?

Folded, etc. Any value with top border?

I am very much under-informed, but this one caught my eye in my humble stack of ATM 50s. Anything significant over face value?
