Just found this 10c piece today.
It's yellowish in colour and this colour is consistent over the entire coin.

Is it worth keeping ?

Weigh the coloured one and compare it to the norm.
If different, could be a keeper otherwise I think it has been in water and discoloured.
My opinion only
It's possible it's been sitting in tea.
Also possible it's been struck on a wrong planchet. As Goldy said, check the weight, if it's right, it's probably just discoloured. :winkextra:
