A REASON TO BUILD

BUILT FROM A REAL
CARD SHOW MOMENT.

On the drive home from a card show, my son had questions about a card he purchased: What was it worth? Was it a good deal? What should he have offered?

Better information while the decision is still in front of you.

A FEW THINGS
TO KNOW.

What is GrailLocker?

A collector focused product being built to identify cards, understand the market, analyze decisions and keep your collection’s history together.

What cards will it support?

Sports, Pokémon, Magic and more. The public preview uses original fictional cards to show the workflow across collection categories.

The iPhone app is in development. Try the sample demo now or apply for beta consideration.

How does beta access work?

Apply with your collecting interests and what you’d like to test. Beta participation is open to ages 13+ with parent or guardian approval for participants under 18. Review the Beta Tester Agreement; an application does not guarantee an invitation.

Where does market data come from?

Pricing sources and update times give an estimate context. SportsCardsPro attribution is retained where shown in the product previews. The interactive demo uses fictional sample values.

Does GrailLocker buy or sell cards?

The public demo does not buy, sell or trade cards. It helps illustrate the questions and calculations behind your own collecting decisions.

GrailLocker started on the drive home from a card show.

My son and I were talking about a card he’d bought. He was excited, but afterward he had questions about its value and whether he’d made the right decision.

That conversation stuck with me. As my boys got into flipping cards, I saw how much they were learning: the price paid, realistic resale value, how easily a card could move, and whether a deal made sense after costs.

I take both of my sons to local shows regularly. We meet great people, talk cards and learn something new. That community and the stories we bring home are some of the things I love most about the hobby.

Values move quickly. Sets, parallels, grades and conditions all matter. Younger and newer collectors have a lot to understand. At a table, they have little time to research it all.

What if they could walk up to a table already knowing what a card was worth, what they were comfortable paying, and what they wanted to offer?

That question became GrailLocker.

I’m building it for my sons, and for everyone in the hobby who wants better information, smarter decisions, and to enjoy the hobby with more confidence.

THE LEGEND OF AURVASK

EVERY GRAIL
HAS A STORY.
HE KEEPS WATCH.

The first pull. The unforgettable trade.
The card you thought you’d never find.

Some cards carry more than a number. They carry a moment. A memory. A chase that became part of your story.

Legend says those moments leave a glow. Aurvask follows it.

Clad in black and gold, his cyan gaze watches the threshold between the treasures you’ve found and the ones still waiting. He stands for the care collectors give the things that matter and the stories worth keeping with them.

AURVASKVAULT GUARDIAN

Some treasures deserve a guardian.
