I know that the silver and gold ones (esp. graded) are still selling for high premiums. A quick look at eBay seems to tell me that ungraded proof clads are going for $30-$40. Does that sound about right?
I would say yes. Looking at the completed listings on eBay...they are selling from about $24-$45. There are quite a few that have sold...so based on the available sample size, I would say that is the right range.
Yeah, not sure if they're holding up the clads, they do show not available until 6/21. My clads did ship shortly after I ordered them, but maybe they're out of them now. Of course there's no rush on the clads, as they're not sold out and they may never be, so there shouldn't be much of an immediate price jump, other than from those that have to have them now.
