I am posting tjis as I see a LOT of comments asking what the abbreviations mean. The grades are based on PSA however the abbreviations are pretty standard in the TCG community Someone who's knowledgeable about the grading system please help, how do the Sub grades give it an overall 4? The average for the card is a 5.75 as u can see in Pokemon Trainer Battle Japanese Pokmon TCG SV9 Battle Partners Full Art Rare Cards Near Mint Singles, No Grading Japanese Pokemon Cards Understanding Pokmon TCG Rarity SGTCGServices
