so very new here, and sent my first book already and looking at sending more.
but some of my modern books "Modern (1975-Date)" type books, that can have a huge jump from 9.0-9.8's and curious how to treat max value?
like a 9.4 may be worth 300 but a 9.8 might go for 1000?
So if I think it'll get a 9.8 should I send it express? or do I send standard because I think it has a shot at a higher grade? how is that handled at CGC, do I get up charged if it grades higher?
