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.

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.

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

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.
