World first coloured circulation coin

The 25 cent Canadian quarter.

Here is a bit off the the Canadian Mint’s website…

“To meet the engineering and design challenges entailed in producing the world’s first- ever coloured circulation coin, the Royal Canadian Mint perfected a high speed colouring process that will generate 30 million coins. The process ensures that the colour adheres to the metal and is resistant against wear from daily use or from exposure to common household products and detergents. With normal wear and tear, the colour should remain for one to three years, but can be removed with harsh chemicals or friction. A permanent poppy has been struck on the coin which will retain its full value, even if the red colour has been removed.”
