If you happen to have a bill with a serial number built from just two distinct digits, I may be interested in taking a look. Bills made only of 1s and 0s are especially on-brand for 1&0.

How it works

  1. Find a bill with a binary-style serial number.
  2. Bring it by appointment for a quick look.
  3. If it fits the criteria, we talk value from there.

This is a side interest, not the main business. The main business is still computer repair.
