JDM auction sheets,
Decoded and Verified
That handwritten auction sheet holds everything you need to know, and AI gets it wrong all the time. Before you bid or sign anything, let a real Truesheet JDM expert decode the sheet and cross-check the photos. You'll know exactly what you're buying, without the costly surprises later.
Real experts, no AI shortcuts
Plain English, no jargon
Photos cross-checked
Know before you bid
Avoid costly mistakes
See the difference a real decode makes.
On the left, the raw sheet most buyers receive. On the right, the same sheet decoded, translated, and explained in plain English.
We translate every grade, code, and note so you know exactly what's worth bidding on, and what isn't.
Half the sheets we get have scribbles, stamps, and crossed-out notes. True Sheet turns that mess into a clear, actionable report. Our buy rate has improved since we switched.
See how AI missed a handwritten note entirely.
The original sheet has a repair note scrawled in messy handwriting. The AI decoder couldn't make it out, so it left it out completely.
Left: the original handwritten note. Right: the AI translation. The missing note was never flagged at all.
