Hi,
Has anyone ever come across one of these quarters showing a river with blue coloring ? I wondered if it was simply a blue pen mark, but I put some wd-40 on it and it didn't touch it. I am tempted to scrub it, but don't want to in-case it actually is something?

The RCM issued its first colorized coin in June 2000, a special collector-edition 25-cent coin celebrating the millemium, with a red flag in the design.
Try acetone or laquer thinner.
Cheers

OK - thanks ; I'll do that.......
