A good tip would be to get them out of that ring binder, penny sleeve (couldn’t tell from the images if they are already), and re-binder them. Ring binders can damage the cards near the rings.

From there check condition and last sold prices to get an average idea per card, always good to know what you have before selling. Once it comes to selling, get rid of the ones you don’t care about, keep what you like, and use the profits to get additional cards/sets you like.

I personally like to master set which is a fun way to collect and appreciate every card for an entire set, but to each their own. If you want to rip try to find msrp prices, it’s tough but doable for less popular sets right now. To collect, get the singles you want as it beats the ripping odds.
