I have been a collector for around 40 years now. Unfortunately I have held to British stamps only for most of that time.
But you mentioned that they are hinged into the albums rather than glued. Had they been glued my only advice would be to throw them away as useless.
The preferred way today is hingeless albums, where the stamps sit in transparent sections without need to harm them by sticking hinges on them.
A general rule, unless you're looking at mid 19th century items, is the higher the face value, the better chance of them having a collectable value.
Most of the U.S. stamps in your picture are low face values such as 3c or 4c. I would imagine issues to be in the multiple millions at least, and therefore unlikely to be at all scarce.
The other nationalities also seem to be low face value.
I'd guess you bought the remains of a youngster's collection after having discarded philately for mobile phones and iPods, or maybe a skateboard.
You could keep them, make them a starter pack for yourself, and build your own collection. Beyond that I doubt you'll see much interest, or income, by selling them. Sorry.

A preoccupation with the next world is a clear indication of an inability to cope credibly with this one.
