As it turns out, it is the most collected card by me. These are the other three I already had.

Before today, the five of hearts was tied with the six of hearts in terms of quantity.

I also have a nine and a jack.

I started collecting cards after I found a handful on P Street in Washington DC years ago. I didn't pick those up, but I did go back to photograph them. I remember some dude walked past me and snorted, "why would you want to photograph those?"
Since then I've picked up all the cards I've found. When I moved to New York I intended to keep them separated, maybe catalogued by location or something, but they've all gotten mixed together.
Heart Backs.
