() There is no protective seal. The inlay in a true crest & seal is a sandwich of an thin opaque celluloid/plastic on which is a litho or printing. The thin printed layer is covered with a thicker, clear inlay. The sandwich is pressed into the chip producing a smooth chip.
The chips for sale are smooth and plain but not c&s.
Take a look at the scan. The chips above are in the same category as the 1970 Burt chips. Crest & seals were made more cheaply over time until they are not really crest & seals. BTW crest & seals, as used by the manufactures (Burt & USPC) were considered any chip with an inlay, no matter the mold type. Crest & seals have a much more specific meaning in use by today's collectors
