Kennedy Half 50th Anniversary

In the Coin World Weekly Update I received in my email yesterday they said that there would be 7 variations of the Kennedy half released in 3 special sets to commemorate the 50th anniversary of the original coin. All of these coins are to have obverses with the deeper reliefs on the original '64 coin. First physical release of two of the sets o occur August 5th to 9th at the ANA World's Fair of Money in Rosemont, IL (too far for me). The first set is a 2 coin uncirculated set with P and D mint marks. The second set is a .9999 gold approx. 3/4 ounce coin with 1964-2014 dual dates. The final set (which will apparently NOT be available at the ANA show consists of 4 coins minted in .900 silver. A proof with P mintmark, Reverse Proof with a W mintmark, Enhanced Uncirculated with an S mintmark, and an uncirculated coin with a D mintmark. No details as to price, mintage limits (if any) how or when to order if you don't go to the ANA show. Unless they have mint to demand limitations (i.e. no limit) this is going to be crazy, especially after the baseball coins fresh in everyone's memory.
