If you're serious about the chip I can spray one down with clear polyurethane and send it your way.... I've done it before for folks that want ummm...errrr...ahhhh UNIQUE keepsakes...
Knew an ex-cop out here that used to do that, mounted them on a board, and put clock works in them. He gave away and sold dozens of them as novelty wall clocks.
He got the idea when he was still working. The cops were in a parade with a Captain leading the way behind the circus critters and the Cap stepped in an elephant turd, slipped, and broke his ankle.
One of the guys went to the circus, got a nice elephant "chip", and they made it into a plaque for the guy. He described it as a foot high, wide, and deep with an engraved brass plate.
Said it was still on the wall when he retired.
