Hi all, I'm back...been far too busy the past couple of days.

A question before I speculate? Can I buy it? That would look nice in my collection. I'll pay the serial number divided by one million which equals $99.999958 or I'll round it up to $100.

What a ripper!

I've looked long & hard at 1999 serials & the highest I could find in circulation was 99999576.
As for the odds & what not...here goes.
1999 saw $50 notes have five seperate print runs, being:
AA99 - DA99 (each print run was made up of 40 prefixes)
DB99 - GB99
GC99 - JC99
JD99 - MD99
ME99 - PE99
It was the third highest print run ($50) from 13 years.
There were 162,479,800 notes.
There were 160 prefixes ranging from AA to PE.
This means that there would be 159,880 (what I call) very/extremely high serials 999,900 to 999,999. (in $50's in 1999)
Yours fits in here!!So out of the 162,479,800 notes in which 159,880 would be very high serials, the percentage is 0.0983753% or just plain 0.1%. This means that at time of release if you only searched the 1999 $50's your chances of getting a very high serial would be 1 in only 1,016, which nearly as scarce as a radar serial.
To get your mind ticking over even further, using the stats from the RBA's latest Banknotes on Issue & the 2011 Vort Report, it'd mean that (theoretically) searching through the entire circulating $50 currency in Australia right now would mean:
486 million $50's circulating
18.0% Macfarlane/Evans (of which 47.8% were 1999)
Which would mean that the 1999 $50's still circulating would be: 41,864,254
Crunching those figures down with the figures of how scarce a 1999 $50 with very high serial number would mean that the following number exist:
41,184a percentage of 0.008474%
or a 1 in 11,801 which is scarcer than a radar repeater i.e 939939 or an 8-digit radar 99011099.
Nice score...I want it

I'm feeling a little jealous right about now...
