A Namco game token I got from an arcade in 1991

I hope this counts, if not I can remove it. This is a game token from an arcade that used to exist at my local mall when I was a kid! It was my favorite place in the mall!
Namco had a chain of arcades in the US, which was pretty wide spread, so I guess it made sense to mint their own coins. Chuck-e-Cheese, another chain of arcades (and other younger-kid oriented attractions), had their own coins too. I think most one-off mom and pop places had a generic coin or directly accepted quarters, but there were probably a few other regional chains which had their own coins.
I worked for the Aladdin's Castle arcade chain, which was also owned by Namco. But they didn't make that obvious in any way.
Oh wow! That's news to me, how cool! :) I love little souvenirs like that, we had nothing like that in the UK :)
