Using Listia to make room

I starting using Listia to shed these John Elway Dupes. So far, I have listed over 120 auctions, and all but 7 have ended with a winner. Pretty cool, now what do I do with "my credits", LOL. I am up to 1993 so far, so next up will be the 1994s. This is going to take all year, ugh.
