Obviously the numbers are handwritten on the base, so it'd be fairly easy to turn a 0, 3, 5, 6, or 9 into an 8. Or possibly blacking out/erasing the first number or first two numbers like 689 or 1189 or 1089. I guess it would depend on what the box has printed on it.
Maybe there's 89 89s out there, haha!
