I never really cared for the idea of colorized coins. I had to get a whole set of 2020 VE Day to fill a hole in my Canadian 5 Cent collection this year.

I found the previous two years in single coin sales.
The 2018 & 2019 Canada Colorized Silver Proof 5 Cents look like this.

I think the quality of coloring on coins can range from garbage to excellent.
The colorized proof silver coins of Canada are very well done.
Years ago I got a Canadian quarter as a gift and that is why it remains in my collection and is still appreciated but I don't think the red enamel paint does much for it at all.

There are American Silver Eagles that get painted up by secondary distributors. They are still an ounce of silver but that's it.
A MS69 or MS70 of the same year is worth much more.
Then there are the lowest forms of colorized coins where a transfer is applied. I never owned one or had one in hand but I bet they look like a newspaper image looked under a magnifying glass.

I am a traditional coin collector, the coins with applied colors were not struck that way, so to me they were altered.
No different than a gold plated
Kennedy half.
People will collect anything and I see I can sell the Canada 5 cent coins at a nice profit at this point. They might hold a premium just because of the lower mintage. I wish they would stop making them though.
It might be a normal option in the future of coin collecting for new issues.
Still, I personally wish it never happened.
