Apple I ‘Hatfield’ Sells for $1.15M at Bonhams, Setting New Auction Record

A rare, fully operational Apple I computer known as the “Hatfield” unit hammered for $1,148,200 at Bonhams on Tuesday, establishing a new benchmark for the pioneering machine that launched the world’s most valuable company. The sale, which coincided with Apple’s 50th anniversary year, saw two determined bidders drive the final price 43% above the auction house’s $800,000 high estimate.

The board, numbered 48 on the Apple I Registry, is one of just 74 verified examples known to survive from the original production run of roughly 200 units. Even fewer remain in working condition with their original documentation intact. This example carries a distinctive provenance: it was originally purchased in July 1976 by Fred Hatfield of New Orleans for $666.60 — a price point Steve Wozniak chose because he liked repeating digits.

What elevates this unit above other survivors is its documentation trail. Wozniak signed the motherboard during a later reunion, and a typed letter from Steve Jobs, dated 1977, accompanies the lot. Jobs urged Hatfield to return the board for a trade-in toward the new Apple II, offering a $500 credit. The letter reveals how directly the founders managed early customer relations, handling everything from engineering to support. Hatfield declined, a decision that ultimately preserved a critical artifact of Silicon Valley’s genesis.

The machine sold with its original operation manual, cassette interface manual, Apple I Owners Club invitation, a period-correct ASCII keyboard, a Sony monitor, and a custom power supply — the last a necessity because the Apple I shipped as a bare board without one. Its 8 KB of RAM and MOS Technology 6502 microprocessor could run Apple Integer BASIC and load programs via cassette tape, cutting-edge capability for a hobbyist kit in 1976.

Tuesday’s result more than doubles the $671,400 the same computer fetched at Christie’s in 2013. That sale followed Hatfield’s own decision to part with the machine for $40,000 in 2012, money he told The New York Times he spent on “nice dinners and nights out on Frenchmen Street” in New Orleans. The escalating trajectory mirrors the broader vintage-computing market, where provenance, condition, and completeness now command premiums that far exceed the value of the components alone.

Bonhams specialist Ian Ehling called the outcome “an exceptional result for one of the most important milestones in computing history.” The auction house had exhibited the unit in New York ahead of the sale to cultivate interest among deep-pocketed collectors. The buyer’s identity was not disclosed.

The record comes as institutional and private collectors increasingly treat early microcomputers as blue-chip cultural assets. A different Apple I, the “Schlumberger” unit, sold for $905,000 in 2014, while a prototype Apple I hand-soldered by Wozniak reached $677,196 in 2022. Tuesday’s price suggests the ceiling for the most complete, best-documented examples has not yet been found.
