Sportscard Guaranty Corporation
Premium card grading known for their iconic tuxedo-style holders
About SGC
Sportscard Guaranty Corporation (SGC) is a respected third-party grading service founded in 1998. While smaller than PSA and BGS, SGC has carved out a strong reputation particularly in vintage sports cards and has seen significant growth in recent years across all card categories.
SGC uses a 1-10 grading scale similar to PSA. Their cards are encased in the distinctive "tuxedo" holders — black background with a white border — which many collectors consider the most visually appealing display for graded cards. The clean aesthetic makes card art pop and has become an iconic look in the hobby.
SGC is known for fast turnaround times and competitive pricing. They've historically been the preferred grading service for pre-war and vintage card collectors, though their modern card submissions have grown substantially as collectors appreciate their consistent grading standards and attractive presentation.
