I thought the very same things at first Greg, but look at how thick the difference is on some of the letters. Even when it gets worn down a bit, I don't think the thickness of the letters will be lessened. I think for the words "NUGGET" and the 25c, there's a very big difference in the two. For the other words, I would agree with you..not enough difference in them to assume there would be a difference after equal wear. Look again at "NUGGET" and "25c".
