Trust & data
A price guide is only worth reading if you can understand what kind of evidence sits behind the number. Every GrailPulse product names its sources, explains its method, keeps outbound links honest, and provides a correction path.
Where prices come from
Figure guides use completed public sold comps where available. Die-cast guides use modeled seed estimates with casting and condition context. CoinSpinner uses published-guide estimates with grade and source context. We do not describe one evidence type as another.
Affiliate hygiene
This hub contains no marketplace or affiliate links at all — every door here leads into one of our own guides. Buying paths, and their disclosures, live inside the guides themselves.
Legal clarity
GrailPulse is not affiliated with or endorsed by eBay Inc. Brand and marketplace names are used only to identify collectible items and the sources of our data.
Quality control
When sold-comp evidence is thin, it should be labeled. When a guide estimate depends on grade or another qualifier, that context should stay beside it. We would rather show a limitation than imply certainty the source cannot support.
Corrections
If you see a wrong variant, a bad photo, a suspicious comp, or a stale price, flag it and we’ll fix it. For now, email hello@grailpulse.com.
