Let me first say that I enhanced the coin color with an imaging program because as you know when scanning, the coin is too dark to view.
Here is the background on the Bank Token..
"The chronic shortage of small coins during the first half of the 19th
century gave rise to a series of attractive copper tokens known as "bouquet
sous." In 1835 the Governor of Lower Canada granted the Bank of Montreal
the authority to issue copper tokens of good weight to meet the need for
small change. The front side of the tokens showed a bouquet of roses, thistles,
shamrocks and wheat and the reverse carried the denomination, "Un Sou,"
hence the name "bouquet sous."
