How to Read a TDG Confidence Score

Collectors see a number and assume it means certainty. It does not.

How to Read a TDG Confidence Score

A TDG confidence score tells you how strong the proof is behind a page. It is not a popularity score, and it is not a guarantee that the price will hold.

The score rises when TDG has clearer media, a better variation match, and cleaner sold evidence. It stays low when the page still needs proof.

What a low score means

A low score usually means the page is still missing one of the basics: exact variation proof, clear photos, or enough matching sales. In that state, TDG can keep the page available for research but hold back the public value.

What a stronger score means

A stronger score means the page is easier to defend. The casting and variation are clearer, the proof is better, and the sold examples line up with the same item and condition.

What pushes the score up

  • Front, rear, base, and package photos.
  • Exact wheel, tampo, color, and base details.
  • Clear condition notes.
  • Better sold proof for the same variation.

What keeps the score down

  • Mixed comps from different releases.
  • Missing package or base photos.
  • Thin descriptions that do not separate one variation from another.
  • Chase or error claims without proof.

How to use the score

Open the value page, read the proof notes, and compare the score with the details you can verify on your own car. If the score is low, save the item as a candidate and add more proof before you trust the value path.
