It's just another in a long line of recent "hoard" coins. Apparently, if you are even somewhat famous when die, any coins you own are now part of a hoard.
The Binion Hoard is the one that I frequently refer to, a large number of "less desirable" coins from Jack Binion's vaults were put into those no-grade Uncirculated holders by NGC. The better coins were given actual numerical grades.
I think in this case it's just a marketing gimmick designed to get fans of the TV show into spending extra money just for the label..
