Greg,
Any interest in this? I've got a few I can sell or trade, or (if you're interested) I would be willing to trade 50 straight up for another fifty of a matching set--my preference is the Jack Todd radial diamond mold without a denomination. Actually, I could live with a 50 cent denomination, if you have a matching set of 50 you're willing to part with.

Let me if you're interested.
