I've been collecting comix for a while. I'm currently valuing a collection I bought for an absoulte steal.
Here are the stats so far.
After valuing approximately 9.2% of the collection I have covered 87.5% of the cost to me by street value.
So far the best books of the lot:
Title: Macross: The Robotech Saga.
Condition: Mint (And I grade harshly)
ROI (Return on Investent): 11,900.00 %
Title: Leonardo, The Teenage Mutant Ninja Turtle
ROI (Return on Investent): 5,500.00 %
Title: Rock'N'Roll Comics
Issue: #1 (GnR)
ROI (Return on Investent): 4,700.00 %
