Me too. I have one of the heavy brass door "R"s with the brass rail handle that attached it to the door. I had said to myself before they closed that if I could have a souvenir of the place that that would be what I wanted, so when I saw that they were selling them at the liquidation I decided to get one.
Of the 330 or so that they had, less than 10% (around 25-30) of them were extra thick plaques and I got one of those. The lady wasn't sure but thought that they might be the older "original" ones (not that there were there when the place opened, of course) and that the company bought the thin ones when they installed them across the property to save money. The one I have is twice as thick and the edges of the "R" square are rounded and polished from use. The thinner ones had sharper edges and corners. As expensive as it was, I'm not sorry I bought it. I was going to sell it on fleapay but I decided to keep it.
I also got a few other branded goodies, too and a cache of $1 and $5 casino chips. I took as many pics as I could but they kept the cage locked for some weird reason (no money in there and the stuff that was in there was supposed to be for sale) so I couldn't get that "Casino" (1995) shot of the cage from inside it -- the one where the FBI is seizing all of the records. I did get into the little room where staff got coins and cash from the cage and was able to take some shots of the inside, just not the angle I wanted.
It was really weird walking around on the second floor where the food court was and being all alone up there. I felt like I was in a Twilight Zone episode.
