Do You Have "Your" Birthday Note?

I just tried an image search for my birthday serial number, just to see if anyone had that number- for 07292000 I got a bunch of pictures of people, for 29072000 I got no results, and for 20000729 I got dozens of pictures of race cars.

Well, you need 4 digits in a row that form a number 2015 or under (20.15% chance), 2 digits that form a number 12 or less (12% chance), and 2 digits that form a number 31 or less (31% chance). That's about a 2.25% chance over all, accounting for all three forms. If you change this to account for months with less that 31 days and for leap years, that number goes to about 2.21%. And that's just if it's a birthday not at all- if you want one specific birthday, such as your own, the chance is 3 in a hundred million (0.000003%).

I think winning the lottery would occur first, because with a birthday note you not only need the right numbers but they also need to be in a correct order.
Finding a needle in a field of haystacks would be easier.

I got a rather grubby one I my change yesterday, with a fairly recent date. Series 09, F07221980C. Anyone born July 22nd, 1980? I have a friend who was born on that date in 2000.

Like this?

Yes I was. The local bank got a bundle of low serial numbers and sold them at face value to Krause Publications. Head of accounting back then was Bob Strand who in turn sold the notes at face value to KP employees with those birth years. Those were the good old days before the corporate mentality took over.

Got some notes issued the same year, but even better, my birthday falls on a national holiday, so my thanks to a grateful nation, once a year.

I got pretty close with this one. My birthday was January 26 1946 so only one year off
