Why Grade Pokemon Cards?
Having your cards graded by reliable card grading organizations tells you what your card's accurate worth is. Along these lines, there is no possibility of underselling your card. ... In the event that you've kept your Pokemon cards in great condition, it's an ideal opportunity to get them out of your closet and have them graded!
A PSA Gem Mint 10 card is a practically perfect card. Attributes incorporate four completely sharp corners (no whitening, no bends, no tears), sharp concentration and full unique gloss still in tact. A PSA Gem Mint 10 card should be free from staining of any sort.
Now when grading Pokemon cards you have lots of options, although if you are shooting for value it changes the game a bit. Some may be cheaper, have a nicer label, a faster turnaround time, but you should really only be considering 2... PSA/BGS. These are due to the fact that they take the cake in reliably and popularity.
