Hello everyone,
I have an uncirculated coin that was originally bright and shiny — possibly brass-plated or golden in colour. Over time, it seems to have oxidized slightly, and a brown tone has started to form on the surface. The coin itself is still in perfect condition with no scratches or wear, but the colour change is noticeable.
I’ve heard of something called “album toning,” but I’m not sure if this is what’s happening here.
My question is:
- Should I clean the coin to restore its original colour, or should I leave it as it is?
- Will cleaning or removing this toning reduce the coin’s value or collector appeal?
I’d appreciate your thoughts and advice, especially from anyone who has dealt with similar brass-coated or golden-toned coins.
Thank you!
