Here is an old scan of mine showing unusual inlay situations. The 2 fleur de lis chips, at the top, have he inlay on one side and the other side is perfectly flat/plain. I once had about 5 of them. Only 2 are left. I was surprised and dissapointed that hardly any interest was shown in them on eBay a while back. (I see I also have one of the common"H" monogram chips with one sideplain.)
