Highlights from Stanley Gibbons' The David Spivack Admiral Collection Part 1 Auction

We're opening up this week's featured lots with this 1916 cover front to London, bearing some rare stamps offered with Gibbs' notes. The highlight here is the £1 (perf 14) which has a very deep purple frame that wasn't known other than on this front. It hit a fantastic hammer price of £4,500, eclipsing it's £1,800 - £2,000 estimate.

Second up this week we're highlighting this very rare Rhodesia: 1913 £1 in grey-black and deep rose-lilac. This unlisted printing from the Die III A Headplate, unused with large part original gum, is one of few recorded examples. Whilst it had an estimate of £950 - £1,100, it hit a final hammer price of £4,200.

Third up this week is this complete mint sheet of sixty in slate-black and dull purple, with sheet number '10' at lower right. This rare multiple makes a splendid item for display, and doubled it's estimate of £1,000 for a final hammer price of £2,000.

This mint top marginal block of four in blue and sage-green, with part imprint, is hinged on the selvedge only leaving the stamps unmounted. It's believed to be the only multiple in this rare shade, making it a great collectors item.

We're closing out this week's featured lots from The David Spivack Admiral Collection with this unmounted, top right corner block of four in darker dull rose-red and dull yellowish green. It's one of the collection's rarer multiples, capturing the magic of the set. It's £2,100 completely outperformed it's £600 - £700 estimate.
