Tech enthusiasts are a passionate bunch, and the rich ones among them are willing to put their money where their mouth is. This is exactly what we see with a signed Steve Jobs business card from 1983, which is posted on RR Auction and is going for $70,741 at the time of writing. What made this relic special is that Job’s business cards from 1983 are a rare commodity and remain in high demand from collectors. It also received a Gem Mint 10 grade — the highest possible rating from PSA/DNA and is certified to be authentic.
