This is one I really wanted but I was too slow. Mark Feld had it but I was too late. It was a perfect match for my type set.
Back in the late 1970s I had a chance to trade my VF 1801 and EF-1815 halves for my choice of either a F 1796 or F 1797 half straight across. At the time replacement value for my two halves would have put me slightly behind on the swap so I didn't do it. Today that same swap would net me about 50K in value. And the 1796...1797 half is STILL the only hole in my half dollar set.
