Serial number on the back

The serial number on the back of the Apple-1 was most likely written by Steve Jobs. According to available information, a forensic analysis has not yet been performed for this Apple-1. However, for some other Apple-1s with a serial number on the back it has been confirmed that it is Steve Jobs' handwriting. More information.


Description

This Apple-1 has a handwritten number on the back like many first batch Apple-1. 01-0052. It seems to be original and Apple-1 #20 in the Apple-1 got the same number which seems to be original as well.
A conversation about the reason for it was going on between Corey Cohen, Achim Baqué and the two owners in 2019. A number of reasons are possible but it will not be possible to clarify it.


History

The Apple-1 was sold to Neal Berger from New Jersey in 2019. Neal Berger also owns the Apple-1 #89 called 'Schlumberger #2' since 2022.
At March 20, 2025 it was sold at auction (RRAuction) for US$ 375,000 to someone in Spain.
