The only one missing from my collection.
The 9.6 that was on eBay with the date stamp may have been the HighGradeComics copy, I was tempted by it myself as I am in desperate need of this book to complete the "keys". But I was also put off by the date stamp, it appears in the "moon" of the cover and even though the book is well structured and looks great (plus its a 9.6) I want this cover to be clean in that respect.
But everyone is right, #227 are hard to come by, I've sold a VFN- raw & a CGC 8.0 in the last year for decent prices whilst trying to pursue at least a 9.4
#232 are easier to find then #227, even though I feel the #232 is the better cover (gotta love that green).
