Sgc

yankees23 · #1 08-05-2015, 01:15 PM

Anyone else notice that SGC appears to be grading a lot tougher these days? I've sent about 10 cards to them this year (all mid to low grade pre-war) and just about everyone has come back with a lower grade than I anticipated. I even sent a few over to PSA and they received higher grades. A year or two ago it seemed the opposite was happening. I just sent them a really nice raw E95 Plank that looked like a 3/4 but they gave it a 2. Anyone else seeing this trend?

Thanks!

no, not really. All the cards Ihave sent in came back exactly with the grade I expected. I think they are strict but fair and unbiased. All of my graded cards are SGC so I pretty well know what to expect.

I think SGC is still as consistent as always.

I do know that my crossover rate from PSA to SGC is only running at around 25%

I had SGC grade 12 cards a month ago and would say all 12 where spot on. I just had PSA grade 5 cards and 4 where 1 to 2 grades over graded and 1 was 1 grade under graded.

I also have always found them to be the most consistent from year to year. Uncanny really but I am thinking maybe they do not have as much turnover on their actual graders? Less graders probably also helps the consistency.

Based on what I've seen over the past couple years in eBay auctions, yes, it does appear that SGC is a bit tougher across the board. Everyone's going to have their own perception or opinion, though, so unless a thorough, unbiased study is done (which is virtually impossible) we'll never truly know.

It's an easy enough experiment to do. Just get a few hundred raw cards, randomly assign each of them to SGC or PSA, wait for them to come back, enter each of the individual grades, compare the SGC mean to the PSA mean (indepedent samples t-test), voila, you have your answer.

In practice it may reliably go in one direction for some issues and the other way for others, but I'd be interested in the main effect (i.e., who is more lenient on average).
