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

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.

Recent confirmed sales

Recording live
No confirmed sales for this card yet We log every UK auction that closes with a winning bid — around 4,600 a day across the catalogue. The first result for this card appears here as soon as one sells.

Fixed-price listings we are currently tracking, cheapest first. Asking prices, not sales, and a sample of what is listed rather than everything on eBay. Each row opens the listing on eBay — HoloHawk earns a commission on purchases made through it, and it never changes the price you pay.

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.
