Great Britain 1883 1s dull green, SG196.
An exceptionally fine and fresh unmounted mint, with full original gum, example lettered "SA".
Superb colour, and scarce in this top condition grade.
SG Catalogue Value: £950+.
Part of the celebrated Victorian "Lilac and Green" issue, the stamp was printed in fugitive ink as a security measure designed to prevent the fraudulent reuse of stamps. The ink was intended to run if soaked from an envelope, with the result that many surviving examples have lost their original colour.
