What the figures are

Collector sales. What buyers paid at auction, converted to pounds at ECB rates of 2 October 2026 ($1.3201, €1.176, CHF 1.0912), then to the London hammer that would have cost the same in total. Bring a Trailer prices get its 5% buyer’s fee, capped at $7,500, added first.

The most a UK dealer can pay. The most a UK dealer can bid at RM London and still break even reselling at the price they advertise: hammer, plus RM’s buyer’s fee (15% to £200,000 and 12.5% above), plus VAT on the fee, equals their asking price.

Estimates. Lot facts and estimates from RM’s catalogue, extracted on 10 October 2026.

Every sale is shown as itself: no averages. A sale is marked when something about it is not ordinary, and the reason is given. Facts only: nothing here is advice to buy or sell.

How we will mark ourselves

One claim is made about each lot before the sale, and the hammer either bears it out or it does not. Where the map said a UK dealer could pay RM’s low estimate, it is RIGHT if the lot sold at or below the highest UK dealer limit on the locked map, and WRONG if it sold above every one of them. Where the map said the lot needed a collector, it is RIGHT if it sold above every UK dealer limit, and WRONG if a UK dealer could have paid it. There is no third answer and no partial credit.

The comparison is made on the London hammer. A UK dealer limit is already a hammer price: RM’s buyer’s fee and the VAT on it have been taken out. RM publishes its results with its fees included, so each result is put back on a hammer basis according to what that published figure includes. A figure that includes the buyer’s fee without VAT is converted; a figure that is already a hammer is used as it is; a figure whose basis we cannot establish is not converted, and that lot is not scored.

Not scored

  • A lot with no UK dealer price on the locked map is NOT SCORED, because the map made no claim to test.
  • A lot that did not sell is NOT SCORED: there is no hammer to test the claim against.
  • A lot withdrawn before the sale is NOT SCORED: it was never offered.
  • A lot whose result carries a label we cannot read is NOT SCORED, and the label is named rather than guessed at.
  • A lot sold after the auction is NOT SCORED: it sold at a privately agreed price, not a hammer.

The rule was written and committed before the map locked on 29 October and before the sale on 31 October, so it cannot be tuned once the results are known. The misses are listed first.

The sale is on 31 October 2026. Each lot's result is added here after it, beside its read.
