Oxidized Capri Cap?

[David]

Age has possibly oxidized the gold cap on my Capri. It hasn't been exposed to anything unusual and I was wondering if anyone has seen this and if there is a quick & easy way to remove 'it' w/o damage. Thanks!

You are the first person outside of my fossil collecting buds to use the word 'patina'... it's not at all common with shark's teeth, but still used... good one Bohdan!
