I don't know. I think it's things like this that get the younger collectors interested. When I didn't know the first thing about collecting, I was all about MS69 and PF69 silver eagles. I had to have every slab that NGC deemed fit to put out there. It got me interested. But as I started researching more and reading more, I realized what an egregious mistake I had made chasing labels instead of coins. That being said, my interest in collecting was stoked. Now I collect what some here may deem "more appropriate" coins, ie peace dollars, mercury dimes, etc. I darn near had a full set of Italian 1 lire coins, which is a far cry from MS69 eagles.
So I say if it gets younger folks more interested in the hobby, then more power to them. And to be frank, some of the stuff these mints put out under the guise of coins I regard more as works of art. I mean, the knight coin posted above is beautiful in an artful way, if not a numismatic way.
