Close, but no cigar.
A while back (days turn into weeks which turn into months which turn into years) I saw this Jefferson at a coin show in Phoenix. I liked it and the price was right so I bought it. I came to find out they came as a set. I had the matte or satin Uncirculated piece from set # 541. It did not have a mate..
Fast forward a few years, probably more than I realize, I saw this on the 'Bay. I pulled the trigger, thinking it was from the same set I had. Nope. Missed it by 10. Anyway, I now have the proof version, albeit 10 numbers apart. I doubt I can get any closer.
I'm kinda wondering if PCGS would put these in a dual holder. Just wondering.
Edit to add pic of reverse.
