Uncirculated bills

I have thousands of uncirculated bills from different countries including a stack of these notes. I don’t know what to do with them. I have to believe these are mint condition since they have never been circulated and never been out of a box. They are even sequential serial numbers.

Sounds like you're trying to sell them here without actually saying that.

Why/how did you obtain them?

I don’t know if I want to sell them or if they’re worth it. My dad gave them to me in a box of baseball cards he got from a garage sale. I’ve had the boxes for probably 10 years and never opened them. They don’t look like they’re in circulation anymore. It’s almost like someone had bought them to make posters with foreign currency because they’re immaculate.
