A very rare variety with an impressive engraver's error.
One of the numerals of the denomination is missing - there is a V instead of VI (a fiver instead of a sixpence).
Missing due to the engraver's error (not placing it on the stamp), not a deficiency effect, as confirmed by another piece, illustrated in Nieczitajla's catalog, minted with the same reverse stamp.
First time in our offer.
