New listings per day

How many new UK listings appear for this card each day. Rising supply against a falling price is the clearest sell signal there is. This counts what we saw, so it is a sample of the market rather than a total.

New UK listings we saw appear each day. A direct count of what the scanner observed, not an estimate of everything on eBay. Source: HoloHawk, observed directly on eBay UK.

Confirmed sales per day

Auctions that closed with a winning bid. A sale we watched happen, not a listing that disappeared for unknown reasons.

Confirmed auction results

UK auctions that closed with a winning bid — not listings that merely disappeared. Observed within three minutes of close, so each is a lower bound on the hammer price.

Where these numbers come from

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

HoloHawk Est. Market Our own estimate, 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.
