I dont really trade by SV ever. BUT, every once in awhile people try to trade with me for a certain card or player that is hot and that card is selling above book. So I do sometimes have to say that I will not be trading that particular card for the current book price because it sells for more and I will just sell it. But if they want to trade for it, it will require a premium or they can wait for updated book pricing. Its just common sense and pretty much everybody does it. I dont think there is a certain way to figure out a specific sv for a card. Its probably just something around want recent ones have gone for. Things happen in sports so fast that can change a players values. Id just do what makes sense, is fair, and makes both parties happy.

Now that is almost a perfect answer, sounds reasonable and fair.
