I was watching it, but when it crossed $1,200 I bailed. It's uncommon, but not nearly as hard-to-find as Blood Is the Harvest or America Menaced. Census shows 19 copies slabbed. I've got two, a 9.4 and a 9.0 copy.
I always wondered if a small stash of uncirculated copies was found a while back - as it often seems to show up in high grade.
Back in the mid eighties, I heard that Geppi had a handful of these copies. I know that Esquire and I have CGC 9.6 copies (shrug)s. I suspect ours may have come from this stash.
