Non-glare is traditionally coated which does effect colors however, there are many other types of glass. Anti-reflective can be good, but it's all relative to the situation, I don't think that would be a large issue except for photographing. There you want to setup a pseudo studio setting. Nothing fancy, but you don't want light bouncing off the glass and you want light consistancy and accuracy. You also want a setup that can be used for nice distortion free angles, of course your lens and settings there are also important.  I think a special note or something along those lines makes the whole thing personal and unique.

No need to think outside the box....
    Just make it invisible.
