(1) Never put chips out in the sun to bask without using a good sun screen.

(2) Don't be a jerk and smoke while playing with your chips, as we should think of those who might want to collect them 40+ years down the road (assumining that person might be younger than the chip).

(3) Use a quality sandpaper so you don't remove more than one-millionth of the chip. You can buy a good millionthometer at The Home Depot for about $12. <g>

Otherwise I have no comment.
