Building trend data — series direction appears once enough snapshot history accumulates.

Heat indexiA 0-100 composite per series: weighted blend of percentile-ranked market metrics — price momentum 35%, sold-comp volume 20%, realized-vs-guide spread direction 20%, auction activity 15%, population growth 10% (inverted — fast grading supply cools the score).

What this measures.Every metric here is derived from market data Coinsel already tracks: PCGS price-guide values, eBay sold comps (a sample, labeled “sold comps observed” — not total eBay volume), PCGS/NGC population reports (updated as certs re-sync, so growth rates can lag), and open GreatCollections auction lots. Nothing on this page is social-media or forum sentiment, and none of it is investment advice.

Auction sell-through(sold vs. unsold rate) is on the roadmap — it requires completed-auction results we don’t yet collect, so it is not shown rather than approximated.
