SGC grades cards consistent and very strict.
They make other companies cards at the same grades look foolish most of the time.
I have done quite well buying SGC cards over the past 20 years.
The tide has turned but alot of folks have not quite figured it out still.
SGC all the way every day.
PS Yes, I own PSA cards because certain cards can only be slabbed by PSA like Vintage autograph cards. I wish SGC would go back to authenticating signatures but oh well! If you are confident and
know what you are doing, you can do quite well buying any slabs that are graded properly but SGC is usually the company that does this.
