Binary is a computer code that only uses ones (1) and zeros (0).
Wouldn't it be more appropriate that only serial numbers with ones and zeros be called a Binary note? Everything else would just be a two digit serial number. BWJM was asking about these "two digit notes" in this area as well.
I'm just asking.....
Who here collects notes with serial numbers having only two different digits?
Eg: 6626622, 4433343, 7711117, etc
Please reply here or send me a PM. I'm curious as to what these notes typically sell for and who might be interested in them.
Thanks!
