This is the parent company of PCGS, one of the the top two coin grading and authentication services.. They also have the same services offered for stamps and other collectibles. David Hall and Van Simmons are both on the board. Some would see this as a plus, others as a minus.
As far as a proxy for PMs, I dont really get it. Slabbing of Au and Ag coins is just one part of a much larger business. Parts of this business potentially being very harshly effected by the economic downturn we all see coming. At one time they ruled the roost regarding baseball cards. I dont think we will see that fad return to prominence again in our lifetimes. In a way you are investing in numismatics, why not just get the actual coins themselves. As for the dividends, they are great, but when the actual NAV of the stock is falling I dont care what the dividends are. I went through this myself with GE over the last 5 years
