Porsches come up for auction all the time. Seldom do we see an entire collection as impressive as this one, though, hitting the block all at once.

These dozen examples of Zuffenhausen’s finest were the property of the late James G. Hascall, former head of a military-industrial defense contractor (now part of General Dynamics) who passed away in August 2016. Aside from his evident specialty in aeronautics and ordnance, Hascall was an avid Porsche enthusiast and collector, who amassed one heck of a collection over the course of his life.

The array is highlighted by a 959 Komfort from 1987 with 4,600 miles on the clock. One of only 242 made, this red example was previously part of the Matsuda Porsche Museum in Japan. It’s expected to sell for between $900k and $1.2 million.

It’s joined by an equally desirable 2005 Carrera GT, with just 120 miles on the odometer. Decked out in emblematic GT Silver with brown leather interior, it’s valued at $800k-1m. And like the rest of the collection, will be offered without reserve.

There’s a pair of 356 cabriolets from the 1960s as well, each valued as high as $200k. And of course there’s a whole mess of 911s, ranging in vintage from a ’69 2.0 S ($160-180k) to a 2016 GT3 RS ($175-250k) that was likely the last he ever bought. Connoisseurs may be most interested in the ’96 993 Turbo S ($325-375k) and the ’89 Speedster ($250-325k).

“It is a great honor to present this beautifully curated collection of cars featuring an important Porsche model from each decade over the last 50 years,” said Gooding auction specialist Angus Dykman. “Each example was carefully selected by Mr. Hascall and his pride of ownership and care is evident throughout the collection.”

Interested? Amelia Island will be the place to be on March 9 when the gavel drops individually on each of the 12. (Photos by Mathieu Heurtault, courtesy of Gooding & Company.)
