Long before there were slabs to protect coins from oily fingers, perspiration, humidity, or any number of other ways those brilliant surfaces could lose their luster there was Lucite.  Not just the old Capitol Plastic holders but paper weights that could hold your birth year set or for that matter any numismatic souvenir suspended both in space and in time encased in Lucite.  Unlike a favorite slab coin these items actually have an artist quality allowing them to left out and about in the home or apartment to be enjoy by collector and non-collector alike.
