I have an ashtray that I took from the Stardust Hotel in Vegas a long time ago. My question is about the Marina printing "Marina Casino Las Vegas" and logo under the black. The ashtray appears to have been made, printed for the Marina, reglazed black, and then printed for the Stardust. I tried to take pictures of it but it can't be seen in them. Does this have any value? Is this rare or are they all like this?
