Ok, sure they are old, rare, and scarce. Ok, maybe they're chips that people don't have and will definately want. But... I can see from the invoice they were only 13 cents each in mint condition!! I think you just do 10 times mark-up and charge $1.30 each.

But seriously...fabulous to find not only the chips, but the file along with it. The information in the article you quoted was also pretty cool.
