Daniel--I'm thinking too there's no harm in including it in the Product List BUT in maybe a special category of "modified" HL pieces with some sort of indication that it's not a real HL gold issue like their other golds (so I would NOT use the G designation). The problem with these modified pieces is deciding which ones to include and that some may require an explanation which doesn't fit the Product List format. But having them in their own category would be a great resource for HL collectors.

Right now I'm feeling that for a piece to be included in the regular Product List categories, it should have been authorized and officially made by HL and sold thru its dealers or the factory (like new society pieces)for a list price
OR given out officially by HL like the "real" gold pieces.
