Hiya. Just have a 'few' get it? :) that have this strange discolouration around the edges. They are not currency and have a U shape mint mark with a Crown. Just curious about the reaction because otherwise the coins have never left their capsules. Sue   Its like a golden bronze effect.. Some areas are purple.. |

It is beginning to tone. A natural condition from exposure to environment. Environment includes holder, temperature, humidity and surrounding air content.

 Toning can be attractive or detractive depending on appearance and collector. You can't remove it without damaging the coin, so you can either stop it from progressing or let it do its thing. |

The Spitfires are staying with me regardless. Out of their capsules and as you say let nature take its course.

The toning at least confirms they are good silver. Some collectors favour colourful toning, to the extent that some unscrupulous sellers artificially tone old coins to increase (theoretically) their value.
If you are keeping them out of their capsules, be very careful handling them, preferably only with cotton gloves. Fingerprints left on the surface will become very ugly over quite a short period of time. If they have already been handled, give them a very gentle clean using spirit or acetone to remove the fingerprint grease before you put them away.

Right the 'Few' are going to get an Acetone bath and stuck in the dark. I do use the cloth gloves Dad left. Some of his notes on his his things were like severe reminders to his self. Capital letter ONLY COTTON GLOVE.
I actually only posted two of the Spitfires. A lot have the effect so will do my best to just dip them and dry. Luckily I have loads of nail polish remover.

Acetone will remove grease, but not the toning. If they have only been handled with cotton gloves, they should not need acetone cleaning and it may take some of the shine off them.

See why coin collecting is a nightmare!
Oddly and only because I know what a Sixpence looks like after my pure exposure to them I noticed a 1954 6p in my change. It actually does pass as a modern 5p. The six is in actually amazing condition for presumably circulating, failing coin vendor machines.
It stood out to me because at some time we made stunning coins.

I really wouldn't even attempt to clean those.
As much as you might remove some of the toning, the potential for ruining it would put me off and it may just come back anyway..

Thx guys.
I put them back and moved on. I did not clean them and back in their tombs.
Now finding ancient wrecked coins that are obviously very old.
I posted in the old coin bit for fun!
