Today, I received 6 uncut panels of 1989 Topps Wax Box Bottoms in the mail (not shown). Although they were uncut, one of the panels had been trimmed around the border just a little to closely.
Although I like to purchase my Wax Box Bottom cards uncut, I am guilty of cutting every single one of them into individual cards. I actually wouldn't mind purchasing cut cards if I trusted the cutting ability of the people I was buying the cards from.
My main point is that I think a thin strip of border should be left around all four sides in you're going to cut them. That way they'll be no question whether too much of the card has been cut off already. If you cut the entire border off, people are not going to be able to tell how good your cutting skills are through an online picture, and will probably shy away from purchasing your Wax Box Cards.
Finding Wax Box Bottoms in top condition can be difficult, since this is the surface of a wax box that gets the most abused. Out of a single panel, you might get 1 or 2 good cards. The rest will probably be creased or scuffed. In many cases, they'll have a wavy cut from someone that had no business holding a pair of scissors.
At first, it may seem instinctive to cut off the entire border around the card. Once have, you'll probably start questioning yourself if you did it right. Then you'll keep cutting, and cutting, and cutting until you know you've messed up the card. The only way to really tell if the card hasn't been cut up too badly is to leave a little bit of the black border around the edges.
The 1987 Topps Wax Bottom cards shown above have all been cut in the manner I described with a little piece of the black border remaining. The 1988 Topps Wax Bottom cards have also been cut in the manner I described, but the black border only exists between the 4 cards of this set with a white border around the exterior of the 4 four cards. That leaves 2 black borders, and 2 white borders around each of the '88s.
Of all the Wax Box Bottoms sets, the 1987 set is the only one that doesn't measure the 2-1/2" x 3-1/2" size. It is also the only set that doesn't contain 16 cards.
