I found this quarter years ago on a salt water beach or in the ocean and like most silver coins exposed to salt water is oxidized black, but unlike hundreds of others that I've found this one has a bright gold toning that has increased over the years that I've had it. I would guess it is too damaged to be of interest to collectors, but I am curious to learn whatever I can about the increasing bright gold toning.



I just wish it wasn't damaged by oxidization.
