When Apple released its first personal computer, the iconic Macintosh 128K, the price tag was a whopping $2,495. A steal at the time, really.

Since then, the Mac, like other Apple products, floated around eBay's marketplace, losing value as other personal computers took its place, according to eBay, which released a few sales stats to commemorate the 30th anniversary of the Mac this week. It seems this computing artifact has been climbing in value lately, fetching an average sale price of $605 in 2004 to $1,598 this year. eBay said its sellers sold five of these models last year.

The Mac 128K was an important notch in Apple's belt, as it set the tone for the company's future products, and Apple is celebrating the release of its original computer with plenty of fanfare.
