Great Britain 1999 £5 brown "Machin" error, SGY1803a.
A superb unmounted mint, with full original gum, horizontal imperforate pair.
Printed by De La Rue in recess, the £5 represents the highest denomination of the Machin definitive series then in use.
A very scarce Machin imperforate error, which is undervalued in the SG catalogue. It was previously valued at £3,000 before their price reductions, yet is even scarcer today than it was 10 years ago.
SG Catalogue Value: £600.
