So I got my 50 card bulk sub back on Feb 2nd and while excited to have it return sooner than expected I was somewhat disappointed about the grades - at first...I received three 8.5's, two 8's five 7.5's and seven 7's. 32 of the cards were pre 1980 so I was under no delusion that there would be a surplus of 9's and 10's. I was initially surprised that at least one of my six 1981 Rickey Henderson or five Harold Baines rookies did not come back a 9, but as I looked closely at my new slabs I noticed that they were indeed not well centered - or enough so to garner a 9. This was a real lesson - that I was not as discriminating as I should have been. Quite a few of my cards would have better grades had the centering been up to par. For these situations where there are centering issues on a higher value card (say easily $100-150+ value) I would request sub-grades assuming that centering is the culprit lowering the final grade.
I do like the slabs better and I say this while also owning both PSA and BGS slabs. I am a collector mostly as I have had my cards for over 30 years but I do plan to sell doubles, etc., to fund the addiction. I do feel CSG grades hard but fair so I will be sending more.
