I certainly don't. If you like the art work go for it. The price is low enough you might as well get it if you like it.
However, most of the inventory is left over from the "poor mans silver" phase when silver went high. I didn't see any of these around then all the sudden, you saw them everywhere. Add to that the people were posting threads everyday about how copper is a precious metal, and the hype, and the drama, and THUNDERDOME! I got tired of them before I ever got the chance to buy one.

Okay, not technically true, I just remembered I have a Lakota Tribe Sitting Bull half oz. copper round. But I purchased that because I got the silver round first and like the design. (The obverse design, the reverse design is rather lacking in aesthetics).
One thing to remember is that copper, not being a precious metal is sold by the pound, not by the oz. So if you are 'investing,' even a dollar is going to be above spot price.
