Are my Pokemon cards worthless?

most pokemon cards are worth less than a dollar...some you might be able to get 5 buck out of them, and some if your really lucky you can gte maybe less than 15...im on to collecting baseball cards now, i have one thas worth 7,000 dollars!!! and a few worth 150, so good luck, a card shop might buy them, but not for much scence not alot of people collect pokemon cards anymore
