Because The Other OptionsSuck

Here's what we do differently. No corporate BS, just honest grading.

🎯
1

Two Graders, Every Card

Two graders look at every card independently. If they disagree, a third breaks the tie. No single person decides your grade.

💰
2

No Membership BS

Other companies charge $100-300/year just to do business with them. We think that's a scam. Pay per card. That's it.

3

Actually Fast

30-45 days standard, 10-15 days express, 3-5 days rush. We hate waiting too, so we built our process to be efficient without sacrificing quality.

👀
4

Full Transparency

Every grade comes with detailed notes and photos. If you disagree, we'll walk you through our reasoning—no corporate runaround.

5

Idaho Based & Proud

We're in Boise, not some massive warehouse across the country. Lower overhead = lower prices for you. Plus, we love it here.

🤝
6

Collectors First

Started by a collector who was tired of the existing options. We know what it's like to spend $800 on cardboard and want it protected right.

Our Guarantee

If we screwed up, we'll regrade it for free. If we stand by our grade, we'll explain why in detail. No runaround, no corporate jargon—just honest communication.

Our promise to every customer
🚀Simple Process

How It Works

Three steps. No complexity. No surprises. Just honest grading, done right.

1
Step 1

Submit Your Cards

Create an account, tell us what cards you're sending, pick your service level, and ship them to our Boise office.

💡

Pro Tip

Use penny sleeves and card savers. We'll ship them back in slabs.

2
Step 2

We Grade Them

Two graders independently examine each card for centering, corners, edges, and surface. If they disagree by more than 0.5 grades, a third grader steps in.

💡

Pro Tip

You can add subgrade breakdowns for $5/card if you want the details.

3
Step 3

You Get Them Back

Cards are encapsulated in UV-protected slabs with tamper-evident seals. You get a digital certificate with photos and detailed notes.
