Sunlight Good for Cards?

[GregMitch34]

Ever hear anything like this? A friend says he occasionally puts a graded tobacco or caramel card--which is a little muddy with age--in direct sunlight for a few hours or more, which lightens it up just a little. Good idea or nuts?

Nuts

if you also water them, it can make them grow. I do this to trimmed cards all the time. Wait. I mean plants.

It might lighten them up in that it fades away the ink.

Litho cards fade in sunlight, though, luckily, slowly. Not a recommended practice.

What David said...


Sunlight is good for cards if you want to fade them. Same with fluorescent lighting. Those slabbed cards displayed in dens and rec rooms will gradually fade, unless someone's put in special lighting or filter tubes over the fluorescent bulbs.

this is the craziest thing ive ever heard. Direct sunlight is bad for any type of collectible.
