I am working on an 88 card set. The 2006 UD Artifacts Auto-Facts Signatures are set landscape style. You can see set details over at the UD website.
The cards are not very thick. About the same thickness as a regular baseball card. Just about any type of top-loader or Ultra-Pro sheet will hold them.
I don't want to just place the cards in protectors and then stick them in a box or binder somewhere. I want to see them. Enjoy them. They are great looking cards.
Currently, I have them in screw-down or magnetic holders. I then wedge them into one of those cheap ass 20 card holders from Michaels craft store. The problem with this system is the design of the frame slots is set for vertical card orientation. So, the cards are kind of sloppily wedged into the rails.
My other concern with "displaying" this set; I don't want the auto's to fade. I know everything fades in light.
What's a good way to display and enjoy baseball cards?
