I am pretty sure that all glass/plactic provides UV protection. Air on the otherhand, I think that's what you need to keep it from. An air tight case will prolong it's life. I'm no art purveyor, or collector so you may want to seek casing advise from a pro. Sweet grab.
I thought my 100th post would be spectacular - but I guess it's just gonna be work.
I own and operate a custom art and frame shop. I have framed and boxed everything from footballs to a Japanese flag from WWII complete with blood spatter and mortar holes. So I'll have to consider myself a pro in this matter. Air tight cases certainly help, but, UV protection is a must and is not provided by all glass/plastic by any means. Plus, your not worried as much about the ball as the signatures.
Light is a common cause of damage to collectors. Paper, bindings, and media (inks, photographic emulsions, dyes, and pigments, and many other materials used to create words and images) are particularly sensitive to light. Light damage manifests itself in many ways. It can cause media and dyes used in documents, photographs, and art works to fade or change color. Most of us recognize fading as a form of light damage, but this is only a superficial indication of deterioration that extends to the physical and chemical structure of collections. Light provides energy to fuel the chemical reactions that produce deterioration. While most people know that ultraviolet (UV) light is destructive, it is important to remember that all light causes damage. Light damage is cumulative and irreversible.

Proper Lighting Techniques
Choose subdued lighting effects that will not reflect into the glass, especially when you are not using reflection control products.
Add a sense of atmosphere by using wall lights or sconces on either side of your framed piece.
Do not display your football in direct sunlight. Even with protective UV-blocking glass, prolonged exposure to the sun’s heat can destroy it.
Use incandescent bulbs to light your ball. Incandescent lights have only 4% of their rays in the damaging UV range. (Fluorescent lights, on the other hand, have a high concentration of UV rays and should not be used to light your ball.)
Illuminate your art at the lowest light level possible for enjoyment.
Unfortunately, the sun is not the only source of harmful UV light rays. All light sources, whether natural or artificial, have some of their components in the ultraviolet range. The most drastic visual effect of exposure to UV light is the dramatic fading of colors.
For this particular football have a case made using museum grade UV blocking acrylic, this will block over 99% of UV light which is known to cause damage over time.
