I have a circulation set. Years ago when I returned to collecting I split up the LWCs between a set for me and one for my brother. I didn’t pay much attention to which dates and mint marks. I wish I had done inventory before I did. I would know to what extent I would be complete. That said, I did find a number of harder LWCs. Larry’s location further establishes that there are many still out there. I get a tad bit jealous of his finds as a result. The infrequency of S mint finds makes it harder to fill out spots here on the East Coast. I assume it would take a several fold increase on volumes done by Larry to find a fraction of the date/mm mix he routinely finds.
