A technically important proof. Ex Perkins Bacon Archives.[NB: listed in the ACSC as BW:70(DP)11Bb. Only 5 examples known.]The damage to the die must have occurred at the premises of Perkins Bacon or immediately after its return toDe La Rue. Correcting the flaw would have been exceptionally difficult and it is thought that De La Rue transferred the die to a roller on which making the necessary correction was less onerous. An impression from the transfer roller was then taken on a flat piece of steel, in effect creating a new die, which was used for the pulls from De La Rues stages 6 to 10. Major Dormer Legge recorded three impressions from the Scratched Die.Provenance: The Arthur Gray Collection, October 2015, Lot 31. $9,00010,000'
