Just a thought, what about the worst things you've sold (for worst prices).
I had about 60 Auto's and 10 GU's a while ago, and I was so keen to get rid of them but nobody would buy them. As most of you know I'm at school so if i need the finances I'll end up having to usually take the best offer unless it's really low.
I had to let 70 Auto's & GU's go for about $150 which I was happy with at the time, but looking back on it was such a crappy deal. It was about $2 each for some awesome cards!!
Included were these-
04-05 SPx Auto/Jersey- Jameer Nelson (BV $40)
04-05 SPx Auto/Jersey- Delonte West (BV $50)
04-05 SPx Auto/Jersey- Al Jefferson (BV $80)
they were all sweet brands too.. a bit peeved looking back on it.. :S
