Signals
Screens that join price, population, pull-rate and sealed-product data in ways a price tracker cannot. Every screen shows its method on the page. None of them tells you what to buy; they tell you where to look.
Pop-adjusted value
liveWithin an era, which PSA 10s trade cheap for how scarce they are?
ln(price) on ln(population), per era. Ranked by residual.
Drawdown vs pop
liveWhich cards are 30%+ off their high while the supply of PSA 10s did not grow?
Observed daily history for the window high; population change between dated reads. Supply column fills in with the second read.
Chase concentration
liveHow much of a set's value sits in its top three cards?
Top-3 share and HHI over every card's observed value. A fragility score for sealed product.
Region spread
liveSame card, Tradera (Sweden) vs TCGplayer (US). Is there a gap?
Median of matching Swedish asks in USD at the ECB rate over the US near-mint market. Gross gap, before postage and tax, which the page says rather than assumes.
Discontinued watch
liveWhich out-of-print sealed products still sit near MSRP?
Era ended = out of print. Unopened price over a cited MSRP; products without a citable MSRP listed unranked.
Box EV
liveWhat is a box worth opened, at today's prices and published pull rates?
Per-card pull odds from TCGplayer's opening samples × observed card values, summed per pack. Three sets have published samples.
