What do you call this part?

I have a pair of plastic inserts (approximately 2" in diameter) with the metal retainers which were used to cover the holes on the door panels for
cars equipped with power windows.
They are from my 1979 Trans Am and are black with the gold bird. I removed them when the car was new and installed tweeters in their place. Now the car is gone and I want to sell them on e-bay, but I don't know what they are called!
Anybody know??
Thanks in advance, Geoff

Escutheons is the GM term they would use. GM still offers these, no fortunes to be made here.
