How To Grade Trading Cards

Here at FLIP COLLECTIBLES SHOP, we believe that once cards are professionally graded, it will protect its longterm investment to maximum capacity. Although we do not recommend one grader over the other, below you will find a list of the top 3 graders (in no particular order), which we have successfully used in the past:
