Method
Our method.
The record
Every result here is a public auction sale of a Banksy print, from 19 Nov 2006 to 30 Sep 2026, 3,473 of them in all. Prices are in pounds and are what the buyer paid all in: the hammer, the buyer’s premium and, where the house charges them, VAT on the premium and the Artist’s Resale Right. Sales in other currencies are converted to pounds at the European Central Bank rate on the day of the sale. If you choose dollars, euros or yen at the top of the page, values are converted from pounds at the European Central Bank rate of 29 Sep 2026, refreshed each month with the results. Lots that failed to sell are left out. Where the same lot appears twice, once through an aggregator and once through its own house, only one is kept.
The value
Each print has a level, and the whole market moves around it month by month. We fit both from every sale at once, so a print that has not sold for a year still moves with the market rather than sitting at an old price. Then each print’s own recent results pull its value towards what it has actually been making, weighted so that last month counts twice as much as a year ago, and held back so a single surprising result cannot swing a quiet print on its own.
The range
No two prints of the same edition sell for the same price, so every value comes with a range: the middle half of where that print’s results have landed around its value. A print with a long, steady record has a tight range, and one with a handful of scattered sales has a wide one.
Condition and the certificate
The condition notes in auction records are loose, and in this record they barely move the price, so we do not price them in. In the Collection, condition places your print within its range: towards the top for a print in excellent condition, towards the bottom for one with damage. The major auction houses only sell Banksy prints with a certificate from Pest Control Office, so a print without one is not valued here at all.
The market
The index is the market part of the model on its own: how much the typical Banksy print has moved, month by month, with every print counting the same whatever it costs. We show it as change: how far the market has moved over the period you choose, and from its peak.
The House Record
Every result here comes from the auction house that sold it. We read each house’s own published results, and each result links to its lot on the house’s site, so you can check any figure for yourself: 2,478 of the 3,473 do.
Each lot is placed on its print from the house’s own catalogue description: the work, whether it’s signed, the edition it’s numbered from, and whether it’s an artist’s proof. Paintings, originals, sets and ephemera are left out, and a lot priced far from its print’s market is checked by hand before it counts.
Houses publish prices in different ways, so every result is put on one basis: what the buyer paid all in. Where a house publishes only the hammer price, we add its buyer’s premium at its published rate. Where it publishes the hammer and premium together, we add the VAT on the premium and the Artist’s Resale Right on UK and EU sales, which the house charges on top.
The record is also checked against independent records wherever they hold the same sale. Where they differ, we go back to the house’s own page, and the house’s figure stands. Results from houses whose records we can’t read directly show without a link until the house confirms them. Each month, after the sales, new results come in the same way, and nothing on the site changes until it has been checked.
Spot something wrong? Tell us, with the sale if you know it. Collectors correcting the record is how a record like this stays right.
