I believe the seller described the corners as Near Mint to Mint+, not the overall condition of the card. You are correct, however, that an SBC 86 would be commensurate with a grade of NM+
To the best of my knowledge, SBC is not the same grading company as SGC. Also, based on current grading standards I would not say that all SBC encapsulated cards are graded conservatively. Although I do think that some of the early SBC grades were better than some of the early PSA grades -- particularly on T206s.
Grading standards have changed considerably since the early 1990s. Some SBC cards are graded accurately, some are not. I do not think it is completely fair or accurate to compare SBC graded cards to those cards graded during the past year or two. A better comparison would be to compare SBC grades to early ASA or PSA grades. Using that barometer, SBC standards were pretty strict.
