Taken from its original description in the Bentley catalogue: "Two significant varieties upon one coin, not only was a letter I punch selected rather than a figure 1 for the date but a letter A was used instead of a V for the initial letter of the Queen's name. As the numismatic trade would say this is a real "after lunch" coin from the engravers of the Mint, and is of the highest rarity."
Estimate: £1,200-1,500
