Nugget mold is far superior to the Caesars mold, at least in terms of flea-bite tendencies. Caesar's mold impressions are too close to the edge and can break off, also a problem with RHC molds.
I have a couple of racks of those spotted Caesars chips. They are some nice ones. I don't hate the new $1's. I guess the casinos are getting wise to the harvesters. I know the spotted with the bird in the inlay was only in circulation for a year and they changed to the unspotted with bird.
