Today I found a 5 cent coin in an Armaguard $2 roll
Yes, this happens way more often than it should given that the weight of a 5 cent coin is
less than half that of a $2 coin. Not to mention the differences in diameter, thickness and colour!! Ridiculous and very annoying!!

And of course 10 cent coins show up in one dollar rolls too.
I'd like a tour of the Armaguard coin rolling process to see just how this kind of thing is possible. When I tip a bucketful of 5 and 10 cent coins into the coin deposit machine at my local bank none of them ever get counted as $1 or $2 coins.
The only way I ever recoup any of my losses is when I find coins in the the reject tray left behind by previous users of the coin machine, even though the machine tells you on multiple occasions to
check the reject tray for any uncounted coins. I guess some people don't count their coins before they deposit them and just believe the amount the machine tells them at the end. Of course coin machines are well known to swallow coins without crediting them to your total, but that happens a lot less often than it used to.
To the OP, I hope you find the occasional 2013 purple coronation $2 among those rolls you go through, otherwise financially it doesn't seem worth it.
