How a card gets into the vault

Each set has anchor cards — Pikachu and the other highly visible chase cards — whose prices are monitored daily. When an anchor makes a sharp move on real sales, the engine scans the rest of that set for popular cards that have not moved proportionally and ranks the largest remaining gap first. If 1st Edition Jungle Snorlax runs, Jungle Pikachu and Eevee get examined immediately — but they are only added if they independently clear supply, gem rate, depth and maturity. The lag is a tiebreaker, never a bypass.

Picks are not decided on the morning they are published. Every day the full PriceCharting Pokémon guide is re-synced and one price mark is recorded for each card in the universe, which builds the price history the screen reads. Once a week a deep pass takes the eligible sets, examines the top chase cards in each of them, and keeps only the ones whose recent history shows a steady decline that has landed near the card’s own low.

Those survivors are checked against cached PSA population and gem rate, and the best of them are written into a multi-week queue with the rationale, filters and risk notes already computed. PSA population is fetched as a slow daily drip against the shortlist rather than on demand, because population barely moves week to week — so a card is only ever looked up once, and no pick waits on a grading-data call.

On release morning the queued card gets one fresh valuation so the vault books a live entry price rather than a stale one.

A book that never sells needs limits on what it accumulates, or a year of “modern alt arts look cheap” quietly turns the whole vault into a single bet. Vault 10 Capital caps how many positions can share a set and how many can share a character, counted across everything already held plus everything already queued. When a card clears every gate but its set or its character is full, it is passed over and the next candidate takes the slot. A better card is sometimes skipped for a merely good one, and that is the intended trade.

Vault 10 Capital does not trade. There is no exit signal, no target price and no sell discipline, because there is nothing to sell — every position is held indefinitely and marked to market. The thesis on every card is a multi-year one: a small PSA 10 float meeting persistent collector demand. Judge the vault on its cumulative curve over years, not on any single position or any single month.

One consequence worth stating plainly: positions are allowed to go against us and stay there. A card that is down is not a failed trade to be cut — it is a holding whose thesis has not played out yet, and it stays in the vault and in the reported numbers either way. Nothing is ever quietly removed.

The entry price booked into the vault is the median of the card’s verified PSA 10 sold prices over the three weeks ending on its entry date, taken from PriceCharting’s completed-sales record for the exact card and version. A median rather than the single last sale, because one mis-scoped listing or one bundle can sit 40% away from the market and we are not willing to book that as a cost basis. When a card is thin enough that no sale cleared in that window, the last confirmed sale is used and the position is dated accordingly.

The daily revaluation uses PriceCharting’s PSA 10 figure for the same card. It is a modelled value that smooths across recent sales — not a last-sale price — which means it deliberately resists single-sale noise and can lag a fast move in either direction. We label it as a valuation rather than a sale everywhere it appears, along with the date it was read.

Alongside it we publish a live eBay ask floor: the median of the cheapest few qualifying PSA 10 listings, filtered to fixed-price US listings with clean single-slab titles and established sellers. Because a PSA 10 of a given card is close to fungible, that floor is a fair read on what you would pay right now. It is still an asking price, not a sale, so it never sets the vault's value — it exists as an independent cross-check. When the two disagree materially we flag it, because that gap usually means the market has moved and the smoothed valuation has not caught up yet.

Population and gem-rate figures come from PSA's public population API. When any feed is unavailable, the vault carries the last recorded figure forward unchanged and says so. No number here is ever simulated or estimated.

Everything above is the complete list of things the screen cares about — there is no hidden extra factor. What stays behind the subscription is the calibration: the exact population floor, the gem-rate ceiling, the volume minimums, the maturity window, the float-growth ceiling, the character and print scoring weights, the trend and floor maths, the anchor and lag thresholds, the concentration caps, and the forward queue of cards already selected. Every entry, mark and result is published in full, including the losers.

The daily job runs before the public tracker refreshes. Subscribers receive the pick and the full analysis immediately; the public portfolio and the public Today's Pick page release the same card the following morning with a shorter summary. This delay is the entire value of the subscription, which is why the sharing policy below matters.
