One of the most comprehensive collections of retro Apple computers and gadgets produced between 1977 and 2008 will soon be up for sale. As reported by PetaPixel, vintage Apple computers will be auctioned in California next month and the entire collection includes more than 500 items collected by the late Swiss teacher and entrepreneur Hanspeter Luzi over 50 years.

The Apples Collection will be auctioned at Julien’s Auctions in Beverly Hills, which will be held live and online on March 30, and the exhibition, where you can see the products, will run from March 27-30.

Some of the exhibits are particularly rare—for example, the 1983 Lisa I computer, which retails for between $10,000 and $20,000. The Lisa I computer is a highly desirable lot for Apple collectors; it is the first personal computer with a graphical user interface, which is known to have been a commercial failure, with only about 10,000 units sold. Very few models survive, although Julien’s Auctions does not note whether this particular example is still in operation.

Other products in the collection are more affordable, including the Apple Macintosh Plus 1986 computer bundled with a keyboard and mouse, now valued between $300 and $500, and a 2001 “Blue Dalmatian” special edition of the now iconic iMac G3 for $200-300.

Apart from computers, the collection also includes some other interesting Apple gadgets. The 1994 Apple QuickTake 100 Camera is expected to bring between $200 and $300, which Julien’s Auctions describes as “one of the first commercially successful lines of digital cameras” before it was discontinued in 1997. The camera had a maximum resolution of 640 x 480 pixels and 24-bit color. Also a 1983-1984 Apple Joystick for Apple IIE or IIC computer systems in original packaging and an original 1979-1983 Summagraphics MacTablet, one of the first commercially available graphics tablets are included.

Some retro gadgets and Apple memorabilia have sold for significant amounts at auction in recent weeks, with an unopened original iPhone selling for nearly $40,000 at auction last October. Just last week, another 16-year-old iPhone was sold for over $63,000, more than 100 times its starting price of $599 in 2007. And these numbers are far from the nearly $220,000 paid for the Steve Jobs’s old tattered Birkenstock sandals last November.
