I can only agree with Bjarne, they are as safe an auction house can be. Several of the music items are checked out by Roger Epperson who is the best in music autographs.
Ive noticed that ICONIC auctions have similar items month after month. I placed a bid on an item last month, and the bid was won at $9k by another bidder. Yet that same item is back on after a month. I do believe now that they have shill bidders on their own site. Its pretty sad cuz they really have some interesting items, but that is probably the last time im bidding on their site.
