How much is a half-point worth?

In this case, about $4,500:

1952 Bowman Mantle SGC 7

1952 Bowman Mantle SGC 7.5

A classic example of the card selling for the price and not the grade (and dispels some of the anti-SGC sentiment with regard to realized prices). The 86 blows the 84 out of the water. I don't know that it justifies blowing past the price of a PSA 8 by 50%, but that puppy is pretty darn sweet!!!

There was an example pointed out in a thread last fall about how sometimes a half-grade card such as an 8.5 will sell for less than an 8 because of the way search terms work, where the potential buyer might only see PSA 7, 8, or 9 with his search but not have the 7.5's and 8.5's turn up in the group he's looking at. For that reason, less people seeing it can mean a lower total sale price even if the card is graded higher. Not sure how common this situation is, but it is something to consider for sure. Look into VCP & ebay completed sales and you can probably find examples.

Sure, the 86 is nicer than the 84, but I don't think its THAT much nicer. I've definitely seen worse 7's.

The 86/7.5 went for $7,110 with the juice. According to VCP, the most expensive PSA 8 / SGC 88 EVER sold went for more than $1,000 LESS than the 7.5! That's bonkers.
