Larena...I'd keep it, it's a nice high serial & also considered to be what some call a semi-solid, being two lots of identical numbers e.g 111222 222888 etc.
Also, I'm glad to see you enter the notes game!
Baanos, I like your work.
Makes it all more interesting.
But a lot of these aren't really relevant with 6 (main) serials that are used (then again in Australia, there were 7 digit notes in predecimal & our current notes can be considered as 8-digit, but it's hard playing the 8 digit game because the first two digits are the years the notes are produced in:
Doubles: Sequences such as 330088 are considered doubles.
Bookends: When the same sequence of digits appears at the beginning and at the end of the serial, like 1039103.
Million numbered notes: Not possible for modern Australian currency but I guess 100000 is worth keeping.
So looking at the more recent Canadian banknotes, they have 3 letters & 7 numbers e.g ABC 1234567
I like banknotes that can spell proper words rather than;
Two letter words such as: AM, BE, HE, HI, IF or acronyms...CD, ID, I'm etc...but sometimes depending on how big the print run is we may not even get many words.
Baanos, a question for you; what would you call &/or consider the following serials as?
003636
008989
Also, would the following be considered doubles?
326532 (in a 6-digit game)
10282102 (8-digit game)
I have seen a rotator or two whilst looking, but I was thinking...would anyone find that interesting or is it just me? They just look so good...just like the numbers that make them up 69...I think it speaks for itself.
Rotator is a radar word! Spelt the same backwards & forwards, just like radar.

I think a lot of you know what I have in my note collection. I've been lucky enough to
