Leaving coins in regular light ok?

Greetings wise coin experts. Another newbie type question. Is it ok to have proof sets displayed in the light for extended periods of time. I am concerned about coins that have cameos that might fade, can that happen? What about toning that might fade? I recently dug out some coins and opened up a box of 1982 proof sets I had. They almost all have nice cameos in the proof sets and I was thinking about displaying some of them but don't want to damage them if I should keep them in boxes instead.

Yes room light is ok. Its the air contaminates that will tone them.

I have heard that sunlight will tone coins. My main dealer tells me that coins they put in the window will tone.

Keep your Proof sets in the box if you don't want them to tone. They will tone in room light. They will tone faster in sunligh. They may not tone if you keep them in the boxes, but it's not a sure thing.

The best storage places are a bank box under consistent temperatures and a dry atmosphere. A closet in your home that is surrounded by inside walls can be good too. If you live somewhere where is gets cold, temperature changes in a closet that is on an outside wall can be fairly large.

The key is to keep the coins out of the light as much as possible and aviod great changes in temperature that can cause moisture to form in the cases. Moinsture promotes tonning.

I would not expect light to affect the coins unless the instensity was high enough that absorbing the light caused the temperature of the coin and its surroundings to increase in temperature.
