Calling Sunday Silverman!

I figured, if A. C. Rancho Mirage has new chips - the Palm Springs casino should, too; and I was right! $1, $2.50 and $5 denoms are now on the tables there. They either have snappier drop boxes or the chips have been on the tables for a few weeks as a number of those I bought turned out to have scratches across the inlays. Folks must have mistaken them for California Lottery Scratchers!

Anyone know how to remove scratches from chip inlays?
