Millionth Notes

A couple of days ago, I posted a few examples of some first notes printed. One of the comments I received was about millionth notes. In Jordan, all banknotes are printed with a six digit serial number. For each prefix, a million notes are printed. So how is this tackled with the 6-digit limitation? Well, upon reaching the highest 6-digit number, which is 999999, a note with serial number 100000 is printed, after which a 6th zero is appended by hand to the right and thus making it a million. This is not unique to Jordanian banknotes and has been known for other countries as well. Below are a few illustrations, the first is a note numbered 999999 while the remaining three are number 1000000. Note the rightmost zero and how it shows slight variations in size, shape, and position.
