Three steps. Real data.

No guessing. No waiting for community votes. AI-powered analysis in seconds.

01

Snap the shirt

Take a photo of the front, or front and back. Camera or gallery. TagCheck handles the rest.

02

AI analyzes everything

Tag type, stitching, print style, fabric aging, construction details. Vintage or reprint. Condition grade 1-10.

03

Get the real price

Sold comps, active listings, estimated value range, last sold price, and pricing trend. All from real market data.

Every detail that matters

TagCheck doesn't just tell you what something is worth. It shows you exactly why, with real sold comps, authenticity signals, and condition scoring that accounts for holes, cracking, fading, and stains.

Like PSA grading did for sports cards, TagCheck brings standardized grading to vintage tees. A shared language for collectors, resellers, and buyers.

🔎

Vintage vs. Reprint Detection

AI examines tag layout, stitching color, single vs double stitch, hem construction, print style, and fade patterns to determine if your tee is genuine vintage or modern reproduction.

📈

Real Market Comps

Pulls sold and active listings from eBay, Grailed, Poshmark, Etsy, GEM, WyCo Vintage, and more. See the actual prices, not estimates pulled from thin air.

🏆

1-10 Condition Grading

Standardized grading like sports cards. Accounts for holes, stains, cracking, fading, distressing, loose stitching, and print wear. A universal language for condition.
