Yes, for sure, cup holders when parked.
I have the sales brochure that explains the purpose of the 3 special models from 1988. 911, 924S, and 944.
I own a 924S Special Edition.
I have customers that own 2 silver cars and a black one here in San Diego. I just met a guy on the phone today who was about to sell his 7, 8 x 16 phonies in long beach. The ad said they were off his 88 944. I called and asked about the car. Turns out he had a Celebration Edition car and didn't know it. Silver. I think he's hanging onto the wheels now...

The term plaque is a mis translation for the large coin. There is no plaque that I know of. Each model had it's own coin.
.... Another cool 944/924S saved/rescued!...
