Hmm, I like playing 21 questions. So, we know it is an error, and has color, but not silver. Is the color gold?
It is a very cool looking coin. @chromerunner Here are slightly larger images, not sure why they look small sometimes when you post. For people wanting a closer look, just click.
It is always difficult to put an accurate value on any error coin. Generally, it is only worth what someone is willing to pay for it, but if it were to be sold at auction and two or more people wanted it, there is no telling how high it could go. Chris
