I tend to work on one set, but I'm easily distracted by a good deal on a nice coin other than the one from the set I'm working on. Right now I'm working on a set of
Kennedy half dollars, but I've had to sidetrack a couple of times for some
Mercury dimes and a couple of
Peace dollars that I couldn't pass up. Now it's back to the Kennedys, but who knows, I may find another coin or two along the way to delay the completion of my Kennedys.
