I do agree with Pain.
We are at the Buy and Sell section, not collector's section. In Buy and Sell, I think it is a marketing strategy to place the item condition to be "mint", ie "as good as brand new" except for the fact that it is being "carefully used".
If I where to grade it at 10/10, isn't it as goo as saying that it is as "as good as new" too? How can "perfect figure" be "imperfect?
If I were to grade it at 9.99/10, just because I have used it, won't the buyer be wondering what happen or what is the flaw of the 0.01/10 of the item? Scratched? Knocked? Dropped?
We are buying via the net, of course there is no way to judge the quality of the item just by reading threads, except "mint" is probably brand new unless one meets an real "unethical" seller.
The above is my humble opinion as a newbie who don't know how to check for flaws of equipment as yet, unless it is disfigured.
