What actually happens to prices when a set goes out of print

"Buy it before it goes out of print" is the oldest advice in sealed investing. It's also imprecise in the one way that costs money: when, exactly, does the price move? We lined up sealed products whose price history spans their out-of-print date — Evolving Skies, Lost Origin, Crown Zenith, Fusion Strike, Double Masters and others — and indexed each to its price in the month OOP was confirmed.

The finding: OOP is a window, not a starting gun

The median product did nothing for roughly six months after out-of-print confirmation — index 100 at +3 months, 104 at +6. Then it repriced: median index 151 by month 9, holding around there through month 18. The market takes about two quarters to actually digest that supply ended — retail stock drains, sellers finish liquidating, and only then does scarcity price in.

For a buyer, that lag IS the strategy: OOP confirmation opens an accumulation window where the thesis is confirmed but the price hasn't moved. For a seller, the same clock says don't list OOP product in month 2 — the repricing you're waiting for historically lands in months 6–9.

Methodology: median indexed price across sealed series whose monthly history spans their OOP confirmation date (small sample — directional, and it grows as our out-of-print tracker confirms more sets). Historical medians, not guarantees. Not financial advice.

FlipBasis runs the OOP clock for you

Weekly out-of-print detection, and every confirmed set is flagged with which month of the window it's in. Signals on Discord are $0.99/month; the full app — fee-true profit, cost basis, inventory — is $4.99/month or $45/year.
