There's a small circle on the N on each side of the $25 and $100 on these new Nugget chips. I stared at it for a long time trying to figure out what it is. Looked like a screw head <g>! Under 10x magnification, I can just barely make out what it really is. It says PAULSON over and over and over. It's the tiniest printing I've ever seen. I wonder what sort of equipment Paulson must have to print that small, that precisely.
