How are final grades determined?
So I just got back a card from BGS where my subs were 10,10,9,9 and logically you would think that he final grade would be a 9.5 right? Wrong, as it came back as a 9.
That being the case, are final grades just arbitrary and not (entirely) dependent on the subs? Seems kind of silly if so. |

How are final grades determined?
The answer is simple. It's on their website. And no, it’s not a basic calculation of adding it up and finding the average. Probably something you should have understood before you decided to grade with them vs PSA. Last paragraph is important.
“ How Final Grades are Determined Here is how we do it! The overall numerical grade is not a simple average of the four report card grades. Beckett Grading Services uses an algorithm which determines the final grade using the 4 sub grades on the front label of the card holder. The lowest overall grade is the first category to observe because it is the most obvious defect, and the lowest grade is the most heavily weighted in determining the overall grade. Example : Centering = 9.5 Corners = 9.5 Edges = 9 Surface = 8 Final grade = 8.5 The reason that this card received an 8.5 is that even though the Surface grade was an 8 (the lowest grade overall), the 9.5 grades on Centering and Corners were strong enough to bring it up a full point to reach the 8.5 level. Another example : Centering = 9.5 Corners = 9.5 Edges = 8.5 Surface = 9 Final grade = 9 Upon first glance, it may appear that this card should've received a grade different than a 9. The most this card could receive was .5 (or one-half grade) above the lowest sub-grade. The Edges were the lowest in this case, hence, the card received the overall 9 grade. Even though Centering and Corners received grades of 9.5, a key point to remember is that the minimum requirement to receive a grade of Gem Mint is to have at least three grades of 9.5 and the fourth to be no less than a 9. Also, please note that the final grade rarely, if ever, exceeds two levels above the lowest of the four characteristic grades. For example, if a card has characteristic grades of Centering 10, Corners 6, Edges 10 and Surface 10, the final grade will be a "7" (of which is exactly two grading levels above the lowest characteristic grade).” https://www.beckett.com/grading/faq Sent from my iPhone using Tapatalk

*On a side note, I've seen a card with a subgrade of 8.5, still receive a final grade of 9.5. I believe all the other subs were 10's (corners, centering & surface). Sent from my N9519 using Tapatalk Last edited by socal805; 04-22-2018 at 01:21 PM. |

What the do is add all all four subgrades and divide by 4 so say 8 9 10 10 the final grade will be 9.25 so a 9

"A card's final BGS grade can be 1.0 higher than the lowest subgrade if: (1) the drastically lower subgrade is either the edges or surface; and (2) the aggregate of the other three subgrades compared to the surface subgrade must be greater than 4. " Example - The general rule is that the card's final grade can only be 0.5 higher than the lowest subgrade; however, in the above Aaron Rodgers card (Grade - 8) the final grade is 1.0 higher than the surface subgrade (7). This is because the lowest subgrade is the card's surface subgrade, and the aggregate difference of the other three subgrades when compared to the surface is 5 (the math is (9-7) + (8-7) + (9-7) = 5), which is greater than 4. |
