I'm glad you posted this. I save em when I find em. To me it looks a lot like the iridescent colors of oil on water.

Why are they rare?
I have seem them often enough to not give them a second thought. Copper naturally discolors like that.
I'm intriqued.

You've seen them often? Well, you're a very, very lucky person! I've looked though thousands and thousands of Lincolns and I may have 4-5 that have this toning. Copper does not "naturally discolor" like this at all. It typically oxidizes and turns brown or is exposed to moisture causing ugly verdigris. You must be confusing verdigris with toning.  |

A soak in MS70 will turn copper into that color.

The MS70 treated coins are actually bluish-purple on a red copper, not greenish.
I will try to find some from my experiments a few months ago. The trick is to get it on camera.

I'm not really into toned coins, but those are rather cool. I have gone through over 350,000 pennies (over 140 boxes) and never found any like that. As usual Thad, nice pics too.  |

The reason they are rare is primarily due to the movement of the coinage. Light layers of Cupric Sulfates or Sulfites do not have time to accumulate so mostly wears off. And then too, the coin has to be exposed to the proper amount of moisture, Oxygen, Sulfur Oxides, etc and for a specific amount of time. In our chem labs we make Cupric Sulfate that has that excessively blue color but rarely on coins. So Thad, just were did you get those anyway. Or did you make them? That 78 and 93 really looks like an artist rendition of a blue painting.  Now if you contact the Franklin Mint you might want to have them produce some plates like that.  I've been collecting for well over 60 years now and only seen a few like that. Maybe not quite that blue, but a little like that. |
