We now have a very limited number of the Iridium-Group of Platinum Group Element (IPGE) sets available. If you already own the more widely available one troy ounce ingots or coins of platinum, palladium, and rhodium then buy this set to complete your PGM 6-pack. It would be a very rare treasure indeed.
