I've observed an increased amount of interest for the 2001 Topps American Pie PAPM3 A Piece of American Pie Elvis Presley trading card, that includes a piece of a leather jacket that he wore.
A whopping four copies of that card sold during the month of June 2016 vs. only one copy during the month of April 2016, as seen in the chart below:
