About Jason

Jason has been collecting cards since 1999 and retro video games since 2008. Based in the Southeast US.

What The Slab is built on verified data, not guesswork. Every article cites real eBay sold comps (with dates and transaction counts), PriceCharting market prices, and PSA pop reports. When I show a price, I can tell you exactly when it sold, how many times, and which listing.

What this site covers

• Pokemon TCG: Set breakdowns, grading ROI, investment analysis, raw vs PSA 10 arbitrage math
• TCG/CCG: Magic: The Gathering, One Piece TCG, Lorcana, Yu-Gi-Oh, Digimon
• Sports Cards: Shipping, storage, grading, market reports
• Retro Video Games: Most valuable games per console in loose, CIB, sealed, and graded condition across 21+ platforms

Data sources

• eBay Browse API — active listings, affiliate-tracked URLs, real card images
• eBay sold-comp insights — 90-day medians, multi-grader pricing, weekly trend data
• PriceCharting — comprehensive catalog for TCGs and video games
• PSA population reports — graded card scarcity numbers

Editorial process

Articles are drafted with AI assistance using a custom content pipeline, then reviewed and fact-checked by Jason before publishing. Every price cited has a source and a date. We never publish articles with missing or fabricated data.

Related project I built

After spending too many nights manually listing my own graded cards on eBay, I built SlabSnap — scan a PSA barcode or CGC QR code, auto-fill the details, and post an eBay listing in under 30 seconds. Free on iOS, Android, and web. It’s the tool I wish existed when I started submitting cards for grading.
