The cards everyone knows
Mantle, Jordan, Griffey. The attention in this hobby gathers around a smaller circle than anyone expects — so we drew it, and now we price those twenty-five cards every morning, at every grade, against sales the auction houses gave us permission to show.

A serious collection is usually understood by exactly one person — which card is the good one, which should never be sold whatever it is worth. Start with that card: we print it at life size, ready to frame, and leave room for the part only you can write.

Why a financial planner writes about cards
The Heirloom Index is written by Gregory S. Ostrowski, a Certified Financial Planner™ professional who has collected since he was a kid, and for a long time now the kind of cards on this site.
When a collection changes hands, the questions a family has are half hobby and half financial — and they get asked of whoever shows up first.
Judge the work first
The research is free to read, and the index has no paywall. It is the same work we do for a client, done in public.
