[goldduck 720]

Hello all, im not well known with pokemon cards, but i have a collection that i started when i was 8 years. Thats why my cards arent in good shape. but i still think they should have a valvue or? I have around 1000 cards there some are new and some are kinda old. I also wonder where i can sell them if they have a valvue at all?
