The toning (patina) certainly enhances the character of many coins, by heightening the fine details in many instances. I find many subtleties of the design I may have missed stand out. Especially beautiful are the coins with nice rainbow toning or hues that blend in to one another. I have a copper or bronze token, not sure which, when looked at is ordinary. However, when tilted in sunlight shows the most GORGOUS shades of blue tones. When I received it I was very disappointed, as it showed no blues as in its ad. While inspecting it, I tilted it and out shone the most beautiful blues. I'm stumped as how this token can have 2 distinct appearances depending on angle of view ? It is a hard coin to photograph to show the toning. Can anyone explain the reason for the 2 visual appearances?
