Hello /vp/! I was wondering if anyone had some advice or tips on selling Pokemon cards. I recently found out that I have a few that are worth some money and I'm trying to figure out the best way to go about selling them. Like is it better to have them graded by a professional or what's the best website to determine a base price to start selling them at?

Pic related is some of the cards I have. Some of them are in better shape than others obviously.
