well theres a couple of places. EBay, or a local card shop. Or if you go to tournaments maybe trade with other people or see if a supervisor will buy them. Remember condition will lower the price. Lastly, maybe if you have any rare cards that you may give to a friend try to sell it to them. Hopefully, you get get rid of the cards a even make a profit.
Reply:Sell them on ebay. Unfortunately it is too complicated to make a ebay account. Also you have to be over 18. Or you could sell them in the streets. Or sell it to your friends if they accept.
