It's an old tradition to wear copper to relieve the pain of arthritis, which is why you'll find a range of arthritis gloves that have copper woven into the fabric. However, a variety of studies in the area have suggested that copper has no effect – positive or negative – on arthritis. So, using copper for pain relief appears to be nothing more than superstition. As such, we wouldn't recommend you specifically seek out or pay extra for copper-containing gloves. Wearing copper gloves won't do any harm, however, so if a decent pair of arthritis gloves happens to contain copper, we wouldn't discount them.
