Coloured $2 coins in Australia are very popular amongst collectors, Some are worth a lot of money, some are not worth much more than face value. But they actually do circulate and you do get them in your change.

Hi Mike,
if they circulate, they are fine with me.
How do you manage to get the color on them when the coin is stroked. I suppose it's always one strike coins? How long time does the color stay?
This I found on internet, https://en.wikipedia.org/wiki/Colored_Coins:
Colorized Circulating Coins
In 2004, Canada, a nation that is always progressive in its variety of inventive coinage, was the first nation to issue a colorized circulating coin. The Canadian 25 Cent Poppy coin was issued in honor of Canada’s 117,000 war dead. The coin had a red poppy emblazoned across the back and a protective coating over it so the color wouldn’t wear off easily. The quarter nearly caused an international spying incident when several U.S. military contractors acquired some in change and thought the coins, because of their unusual appearance, may have some type of nano-technology transmitters on them. The contractors reached out to the U.S. Department of Defense and were assured these coins were not espionage equipment.
Since that time, the Royal Canadian Mint has utilized that technology on numerous occasions to create different colorized coins. Some of the most popular coins have been the colorized Maple Leaf silver bullion coins, with their bold, bright and seemingly natural colors.
Australia has experimented with colorized coins and its engraving technology. They developed an idea to vary the depth of the engraved subject to enhance the detail and colors.
Countries that you wouldn’t expect joined the rush to authorize colorized coins – Mongolia, the Cook Islands, Congo, Liberia, the Northern Mariana Islands and Cameroon are just a few.
Today there are close to 50 sovereign nations that offer colorized coinage and there are many hundreds of different issues. The topics range from world leaders to cartoon characters, from race cars to every conceivable type of animal or insect. Everyone strives to find a topic that hasn’t already been covered. In addition, many colorized coins also come in a wide variety of shapes including guitars, animals and cars.
MC Garofalo is APMEX’s Director of the Ecommerce Experience and has been in the precious metal and rare coin business for more than a dozen years. “The growth of APMEX’s business in colorized coins has been phenomenal. Both young and old customers love their favorite movies, video games and superheroes! The nostalgia is represented on these bright, beautiful coins and rounds. They love owning them.”

I still don't know, how it's done!
Thanks
