> are either depreciated in value versus a bullion per weight?
They will always be worth spot price of silver at a bare minimum, but usually a bit higher because of manufacturing costs. IOW, there's no depreciation at all involved. Over the long haul they will only appreciate in value as the dollar depreciates and silver becomes much more scarce.
