I recently created a new workbook in Excel, which allows me to combine my yearly noodling stats into a single set of data. As a result, I now have a much larger set of stats to work with, so I decided to share them with you. Please note that they are only accurate for COINS dated 2015 and earlier, because apart from the Changeover 50c, later coins had not been released when I began noodling.
I've also added some stats for banknotes, but similar caveats apply. The $5 note explicitly excludes those dated 2016, and because I stopped noodling them on the day the new ones were released, I have no information about whether the 2014 and 2015 ones were ever circulated (although I certainly doubt this). As for the other denominations, they are only accurate for NOTES dated 2013 and earlier, because the 2014 and 2015 ones had not been released when I began noodling them.
Without further ado, here are my results:

5c Coin

10c Coin

Notice the steep drop between 2010 and 2012. This confirms that the 2011 10c is very scarce.

Note the steep drop between 2009 and 2013. This does not accord with the production figures I've obtained from the RBA, which show the 2010-2012 figures to be much higher. Has anyone else noticed a similar drop during this period?

Terrific work Hercules!
Interesting with most of the note denominations how they stacked up in terms of age.
Pedro
Yeah. The fifties and hundreds seem to last a lot longer than the other denominations. According to the RBA, this is because people tend to look after higher denominations much better than lower denominations, and are much less likely to put higher denominations in their pockets. The hundreds have the longest life of all, because they rarely change hands, and don't have to cop the abuse of ATMs. That's why it's so easy to find $100 test notes in good condition, despite the fact that they were released over 20 years ago, and make a $50 profit off them. If you had the money, $100 note noodling would be the most profitable of all. ;)
Great work Hercules! I enjoy the detailed breakdown in your graphs. Lots of work there!
A good looking stat sheet. Maybe I should have done my stats the same.
May I suggest at the end of each coin stat that you include the number of coins actually searched. IE: Total $1 coins searched.
Have you any problems if I set up a new stats table like yours for my own use? I only record total numbers of coins each day rather than split them into years as you have done.

I did. It's called the sample size. However, please think of it as the number of coins found in 5c/10c/20c/50c/$1/$2 rolls, rather than the number of 5c/10c/20c/50c/$1/$2 coins found in rolls, or the number of 5c/10c/20c/50c/$1/$2 coins found in 5c/10c/20c/50c/$1/$2 rolls, because these are not synonymous. :ok:

Not at all. I don't have a copyright on it, so you're free to set up your own tables if you like. :)
Many thanks for the response above.
However, do you find it very annoying with the number of foreign coins you are finding.
When found, do you put them back into the sack for recirculation or what?
The foreign coins aren't annoying, just amusing - especially when they appear in Armaguard rolls. I keep all of them because of their low face value, and add them to my foreign coin collection. I'm hoping I'll soon have a complete set of Kiwi 5c, 10c and 20c coins dated 1967 to 2005. :)
A lovely presentation of your stat's Herc! Keep up the good work.
