How Are .5 Grades Priced?

New member here, so forgive me if this has already been discussed in the past. Just got my first PSA grading submission back, and one card, a 1972 Roberto Clemente, got a 6.5 grade. In looking at the price guide, I didn't see prices for .5 grades. How can I price a 6.5 grade?

In other examples, such as rarities, NV is right.
Offered it on eBay with a opening bid of $200.00 and no bites. Was offered $125.00 for the card.
Every one wants a bargain.
Good luck with your Clemente.
