A California electronics recycling company has a $100,000 check for the woman who unwittingly donated a vintage Apple computer worth twice that amount.

A woman dropped off boxes of old electronics to the Clean Bay Area recycling company in early April.

A few weeks later the company started going through them. That is when an Apple I built by Steve Jobs, Steve Wozniak and Ron Wayne in 1976, was discovered, according to the San Jose Mercury News.

Vice President Victor Gichun sold the rare find to a private collector for $200,000. The company policy is to split proceeds 50-50, so they are trying to find the woman who did not leave her name or get a receipt.

"To prove who she is," Gichun said to the San Jose Mercury News. "I just need to look at her."
