David, I have a Orlean's which is also a copper rim no doubt. In chats with other collectors I beleive there are a few misc strikes out there that are of the copper rim era. Even though they are not on the lists of coppers. My guess along with others is that as the copper rims were all being used a very small few were just used here and there. Which is how you get one from the Venetian, I have one from the Orlean's and I expect a few others here and there.
