Love it

I thought the slabs were very clear and graded correctly. The response time of the Sigma crew was quick. I liked the ability to input the cards through their site as well. I’ve already purchased my 2nd batch! My daughter loves the Duck!

Awesome

High quality grading at an affordable price. Accurate grades with quick turnaround.

Fast returns and decent grading

They look great as always!

easy to submit

Very satisfied with the grading and quality.

I am so happy with my graded card! The quality of the case and label are excellent. I had my card back in hand within four days. The grade was accurate, return shipping was free and the cost if grading is $8 which is a fraction of the cost compared to the inflated pricing if other companies. Equal quality for a great price!

Happy will send more cards your way soon

Loved the price, convenient shipping back. Great turn around time. Hope you have more discounts. Although I've never graded a card before, because of the price

Great value. Very quick turnaround time. Friendly service. Will use them again and recommend to others.

lightning fast turnaround. Fair grading. All any collector can ask for.

Perfect

Another great slab and quick turnaround by Sigma grading. The green bumper that was thrown in to match the green Prizm Arch Manning made the card really pop! Can’t wait to submit more cards and see the results!
