Great Britain 1969 Jersey 10s "Royal Court", SG28a
A superb unmounted mint, Post Office fresh, bottom marginal example with full original gum.
The most famous stamp error from the Channel Islands with iconic status. It is a very rare error of colour with the border printed in green instead of slate blue.
A magnificent example of this key Jersey rarity, that occurred when during the final printing one sheet of 25 was accidentally fed into the press which had been set up with the green background of the 50p value.
