New listings per day

Building
How much new stock hits the UK market each day The scanner records every new UK listing it sees — around 13,600 a day. This charts how many appear for this card once the daily rollup has readings for it.

A direct count of listings we saw appear — not an estimate of every listing on eBay.

Confirmed sales per day

Building
How often this card actually sells We record roughly 4,600 UK auction outcomes a day across the catalogue. This charts how many close with a winning bid, day by day, from the first confirmed sale for this card.

Only auctions that finished with a bid count. A listing vanishing is not proof of a sale, so it is not counted as one.

Where these numbers come from

Three independent readings, shown side by side rather than blended into one figure:

HoloHawk Our own market price, from live UK listings
PriceCharting Published reference price, USD converted to GBP
PulseTCG Published reference price, natively GBP

A reading is stored only when a price actually changes, so flat stretches mean the price held — not that data is missing. Where a source has no history for an item its line is absent rather than flat. Confirmed sales are UK auctions that closed with a winning bid, observed within three minutes of close, so each is a lower bound. Live listings are asking prices, not sales. Supply and sales counts are direct observations — listings we saw appear and auctions we saw close with a bid. We do not infer that a listing sold because it disappeared, so nothing here depends on that guess.
