Got these coins at car wash today never used them when I got home I throw all my change into containers to check later anyway this one stood out more of a darker gold colour than the regular light gold ones anything new or common
With the picture it looks a little different but in hand it is very noticeable any idea's
That's completely normal. Sorry to be the bearer of bad news, but that isn't anything particularly special. It's just toning. This phenomenon is also commonly seen with loonies, and I'm sure you'll be able to find a few examples within your change of some that are darker and lighter. It happens all the time.
