10 Dollars

The 2013 Canadian polymer $10 is part of the Frontier Series, the Bank of Canada's first fully polymer issue, which replaced the long-running cotton-paper Journey Series that itself had only finished rolling out in 2004. The switch to polymer was driven less by counterfeiting — Canada's fraud rates were already relatively low — and more by durability economics: polymer notes last roughly two and a half times longer in circulation, which matters considerably for a high-turnover denomination like the ten.

The Canadian Bank Note Company produced the Frontier Series domestically, a point worth noting given that earlier Canadian issues had frequently been sent abroad for printing. The transparent window is integral to the substrate rather than applied as a patch, which distinguishes it from some contemporaneous polymer adoptions by other central banks.
