Is it a gum stain or wax stain? Not that it makes difference I guess. It's a nice card, and if you can get the card for a reasonable price I would buy it. If you need to resell you stand a better chance of recouping what you spent. If you pay the going rate for a 5.5, I believe you will have a hard time recovering what you spent. The current bid price seems low right now, and that ( I suspect ) is due to the staining on the back and keeping most bidders away. Could be the same situation if you buy the card, and have to resell down the road. Flaws keep serious bidders ( spenders ) away.
