Not only are the mintages low 2012 sets: mint, clad proof, and especially silver proof are just hard to find because any dealer will tell you usually you get just a few at a time like five or less. At smaller shows (outside of a big metro area like Kansas City, Milwaukee, Twin Cities . . . dealers will often buy a year run just to get the 2012 sets they want and then wholesale the others out. If the sets are pain to find finding the proof singles is even worse. I bought a 2012-S Silver Proof Kennedy and put on my USA Coin Book Website and it sold in one month. Both Proof Sets (CLAD INCLUDED) are so expensive that few people break them up. Many collectors that say bought four or five of each three years ago broke up one clad and one silver for their sets and they are sitting on the other four because so far they have held their value. Time will of course tell if they go the way of the 1995 and 1999 Proof Sets. It could very well be a deal like the 1970 Mint --- it other words the sets stay hot for the next 10 or 15 years A) the price drops or B) a future set with a even lower mintage or a cluster of about 2 or 3 years close together overshadows them (kind of like the 2008 and 2009) or C) maybe a little bit of both of the former.
