Rob, I 'd like to congratulate you here too, after saying so on the OBC thread.
That's a great run!
I'm down to 27 which includes the 1952 low series but I haven't gotten one in months...maybe I don't want it to end

Of course, to me...it's a side project to go after the Topps run since the T's and the E's really do it for me
I might be able to help with 52 lows, but there are some Real Tipton mints 10 or Tipton gem mint 11's in there so you'd probably want to upgrade before you pull them out of the envelope LOL.
Once again, congrats on a very cool accomplishment!
