Origins: In 2011, Canada began replacing its existing supply of paper (actually cotton) banknotes with ones printed on a synthetic polymer, starting with the $100 bill in November 2011, then the $50 bill in March 2012. (The $20 will be issued in November 2012; the $10 and $5 will follow by the end of 2013.) These new bills should stand up to handling far better than their cotton predecessors (lasting up to
The new bills became the subject of gossip when tales of their melting into puddles of plastic circulated widely during the summer of 2012. A bank teller in Kelowna, British Columbia, said she'd heard of instances of $100s melted together when left inside a hot car. A man in Halifax, Nova Scotia, asserted he'd laid his wallet on a toaster oven after using that machine to brown a bagel, then noticed three of the new hundreds so warmed had taken on the appearance of a Coke bottle.
"Puddled" currency tales began shortly after the new plastic $100s were released when a man in Cambridge, Ontario, reported his Christmas bonus of eight new $100 bills that he'd placed in a tin box near a heater had melted.
Precious little can be manufactured in such a way as to render it entirely indestructible, and certainly anything fashioned of plastic will deform or even melt when subjected to a high enough heat. The new Canadian bills are made of polypropylene, a substance that has a melting point of 266°F. While they can melt if taken above that point, only rarely is a banknote likely to be in such an environment. The internal temperature of a car left parked with its windows up on a hot summer day isn't going to reach that level
Prior to their introduction, the new Canadian banknotes were subjected by the Bank of Canada to all manner of tests. They were boiled, frozen, and run through washing machines. They were subjected to rides in a tumbling mechanism filled with coffee grinds, marbles, bolts, and synthetic sweat (meant to simulate the effect of being left in a pocket).
"The new polymer notes have been rigorously tested in very hot (above
A representative of the Bank of Canada told us:
This is straightforward, simple chemistry. We have done extensive and rigorous testing of these new polymer notes prior to issuing them, including exposing them to extremely hot (140°C / 284°F ) and cold (-75°C/ -103°F) temperatures. In other words, polymer bank notes cannot be affected by the types and levels of heat as has been suggested in recent news reports.
Moreover, bank notes printed on polymer material have been used in many other countries for years; in places like Australia, Mexico, Nigeria and Singapore, all of which have climates far hotter than in Canada.
Canada has experienced its difficulties with currency revisions. A loon appears on its
