I have seen a few coins lately that seem to have an irradescent shine to the surface? Like this picture of a Sacagawea Coin... this is on ebay...It was call a Rainbow Coin. I just thought that it was heated up by anyone who decided to do so... I also have in my possession a penny with the same glow... Please Help me, I'm confused....

You're probably right. Just an artificially toned coin. Others would know better than me.

I think there is a tread in this forum about toned coin for me they look good you can also see images on the gallery of some of the member.

That dollar would be Heat and / or Chemicals. . . . .

I have an ethiopian coin that is not silver but toned like that...it was made into a necklace by welding a hoop on it...I assumed that welding heated the coin and caused that toning...

You can take a pen toarch from a crafts shop and make rainbow coins all day long to sell on Ebay. . . If your real good you can make the lamination Rise to form a nice bubble.

Thanks a bunch guys/ and gals!! It confirmed what i thought!! Thank you!!!
