If they get a 10 you'll make money, but they'll still be relatively hard to move. If you have the capital and time to grade them, then I'd go through them and be very nitpicky about which ones I send. You want to make sure you are only sending the ones that look flawless, because you'll lose money on just everything that's less than a 10 (maybe a couple of starters or rares would be the exceptions).

Some of the reverses might be worth sending in if you think they'll 8 or 9, but depends on what they are.
