Rough estimate on the worth of my collection?

Hey,
I've just undusted my pokemon card collection, and I'd like to ask for a rough estimate on what its worth (I have a guy offering me 2€ per holorare, but I think thats quite a bad deal^^). Now mind, they are not in a perfect condition, would say near mind / slightly used. Also note that many cards are german pokemon cards. its 25 holorares, 25 rares (1999) and 24 rares (1999-2000). I think uncommons and commons as well as energy cards are near worthless? I also made pictures and uploaded them to google drive, but I must not post links^^

I couldn't tell you on a lot of these without seeing them. The european market has always been a little weaker (some guys at my league run spanish trainers because theyre so cheap and league legal) You could probably push to 4-7 euros on the better condition ones or try and sell them to the British market, they might give you a fairer price.
