It appears that Bernie had got his coins slabbed for the sale and interesting to compare the gradings against previous provenance, e.g. the 1863 die 2 was described as VF in the Laurie Bamford sale but had been graded as AU details-cleaned for Bernie's sale. And the F76 was EF in Laurie's sale but had improved to Unc in Bernie's sale !
As they say, grading is in the eye of the beholder.
