The £1 rarity will auction alongside a Penny Black pair in
Spink's sale of rare stamps in

There is another reason why a bidder might be keen to get their hands on it: it was owned by the greatest stamp collector of recent times, Bill Gross, until 2007. It is estimated at £15,000.
Also appearing in the sale are two high value stamps from the 1867-83 series: a greenish-grey 10 shilling stamp and a brownish-lilac £1. Both have a small part of their original gum.
Each has a minor flaw: the £1 stamp has the faint trace of a diagonal bend whilst the 10 shilling piece has a minor abrasion by the chignon of
The Stanley Gibbons prices for the two stamps are £50,000 and £80,000 for the 10 shilling and £1 respectively, but here they have guide prices of £12,000-15,000 and £15,000-18,000. This indicates that they might be particularly worthy of consideration as a tangible asset.
The £1 variety was also once the property of Bill Gross, and before him it was in the collection of Alfred H Caspary, whose collection of American provisionals was legendary.
