WHERE I AM ATIn the past few years I have filtered through hundreds of thousands of dollars through my retail business. I really wish every dollar that came through the business I could keep, but I do get paid so it's a job with benefits. Thoughout the past few years I've received some very scarce notes including:
WHAT I HAVE FOUND$5 - FIVE DOLLARSKC95, EA98
I've also had many recent near UNC $5 AA & last prefix notes.
$10 - TEN DOLLARSDF94, DF97 (which Trevor Wilkins paid $310 for in good Fine cond)
I've also had many recent near UNC $10 AA & last prefix notes.
$20 - TWENTY DOLLARSDA95
$50 - FIFTY DOLLARSVG95x3, JC97 (just last week), JC98
$100 - ONE HUNDRED DOLLARSJK96x3, CF98x2, JK98x2, JK99x4
Test First Prefix: AN96x3, Test Last Prefix: CS96x3
Test Prefixes: too many
PROBLEMSThe major problems with collecting polymer notes is;
- The cost
- The condition of the scarce or rare notes
- Finding the real information & a real indication of value
- Grading the notes
SERIAL NUMBER COLLECTINGI also amongst collecting the scarcer first & last prefixes, collect special serial numbers such as:
- Radars: Mirror image e.g 124 421
- Repeaters: 124 124
- Radar repeaters: 121 121
- Ladder radars: 123 321 or 876 678
But there are so many other types where you'd have to pay a huge premium for. The following are what I'd love to chase if I had the money to do so:
- Solid serials: 888 888
- 8 Digit Radars: e.g BD10455401
COMMONALITY OR UNCOMMONALITYThe commonality of some of these notes is so scarce. There are 9 solid serials in every 999,999 notes which makes them 1 in 111,111. Radars & repeaters are 1 in roughly 1,100. Radar repeaters 1 in roughly 11,111. But the numbers go on & on. I end up getting confused amongst trying to work them out.

I have to sit down again one day with a clear frame of mind & work it all out. As for your statistics, the RBA website has a banknotes back-end which has the print releases of notes from the 1992 beginning of the secure polymer note.
