ABOUT US

Simply put, we were tired of inconsistent and expensive card grading. We knew we could do it better for less, so we did!

The GSL Grading System, as described on our Home page, is an engineer-crafted system meant to grade cards fairly and repeatably.

• GSL never forces mail insurance if you don’t want it. This means a card doesn’t have to be worth a billion dollars to be worth grading.

• If you feel another grading company didn’t give your card a fair shot, we are always happy to crack open a graded slab and re-grade it for you, per our excellent standards.

• We’re always here to help if you have questions or concerns.
