I noticed, so far in 2014, there were hardly any new prefixes for the Polymer $5's and $10's. The $10's, I can fully understand, as there is a lesser need for them, and based on trends from as far back as 2012, it seems as if new $10 prefixes occur approximately every 9 months. Every so many years, demand for the $10s drop (as the stuff that $10 bills buy now, $20 bills will buy then), and the gaps between new $10 prefixes broadens by about 3 months. If this trend continues, new $10 prefixes where I live may end up becoming an annual event.
As for the $5's, I hardly saw any fresh new Polymer $5 prefixes this year so far - I may have seen very small ranges of HBL and HBM, but nothing otherwise - and 2014 is quickly approaching the halfway point. I learned from a co-worker that she sees toonies in her change less now. Makes me wonder if that could be the reason why the number of $5 bills in circulation across Canada was at an all-time high in 2012? But I wonder if many of the paper $5 bills in circulation are still in good quality, and that may be the reason why there has been no movement in new polymer $5 bills coming to my region so far this year. I also noticed that the majority of Polymer $5's I see in my change are HBJ prefix. If I see a Polymer $10 in my change, right now the probability is over 95% in favor of prefix FEW. but at least the probability of seeing an HBJ on a $5 bill in my change is lesser.
If a new $10 prefix does come my way in July or August, I think it will be then that I will safely declare that new $10 prefixes will only be delivered to banks in my region approximately every 9 months, and that prefix will likely be the only new $10 prefix seen in my region this year. It seems as if I really appreciate the $20 bill now more than ever, and as of lately, I may be losing interest in the $10 bill.
