According to the Associated Press, a functioning 1976 Apple I sold for $668,000 at a German auction (see story). This computer originally sold for $666.66 as a kit.
One wonders about the highest price a 1978 2-XL has fetched. I have one with a low serial number (13587), but I only paid $25 on eBay.
