Old Pokémon cards value - With wear

[SellingCardsSweden]

Hi,

I was just at my parents house and I found my old collection of pokemon. I looked some of them up (the ones that are shiny, and the ones that have a star instead of a cirkle in the bottom right), and it seems some of them are worth a couple of dollars.

However, my cards are not even near mint condition, i have not had them in plastic pockets, nor a binder. They have been stacked on each other in a wooden box, and they have been played with at school 15 years ago.
Most of them are from 1999 - 2004.

So my questions are;
(1) Do Pokémon cards still hold any value even though they are not in good condition?
(2) Can I sell them all together, or do people only want the ones that are rare?

(I also wonder the same about Yugioh)

I attached three pictures, one of the fronts of some cards, one of the back of some, and one of how i have stored them for the past 15 years.

Wow nice find, but no the value drops a lot when the condition is a bad as those are. There are some that are more sought after even if slightly damaged, so look for anything with a rare symbol on it for starters.
