Auction preview: Seaway Inverts, imperf sheet of 100 Bluenose stamps offered by Rasdale

An imperforate, never-hinged full sheet of 100 1929 50-cent Bluenose stamps (Scott #158a) will be offered by Rasdale Stamp Co., of Westmont, Ill., during a two-session sale on Feb. 18-19.

The sale is highlighted by Rasdale’s recent acquisition of 140 cartons of material kept in storage since the early 1970s.

“The first thing we unearthed was a complete imperf sheet of 100 of the Canadian Bluenose, only two have been reported,” reads the auction catalogue.

This sheet of 100 – Lot 1287 – is being offered with a minimum bid of $7,500. It’s accompanied by a 1970 letter from noted Canadian philatelist and dealer Kasimir Bileski, of Winnipeg, who writes, “… no one anywhere, collector or dealer can produce a complete post office imperforate sheet of any value … Enclosed is officially classed as a sheet comprising 2 panes of 50 each of this value.”

Bileski, who died in 2005, is remembered for his discovery of the now-famous 1959 Seaway Invert.

Also found in the 140-carton acquisition were both mint and used 1959 Seaway Invert examples (SC #387a), which are being offered as Lot 1298 and 1299, respectively. The mint example has a pre-sale estimate of $9,500, and the used example has an estimate of $7,500.
