Neat! coin that is tougher to find than you think.... Haven't seen one in a long time....last one to auction at Heritage was in 2007. Before that was 04. Neat ddo to say the least...I think I got it at a steal. http://coins.ha.com/common/view_item.php?Sale_No=68124&Lot_No=64082
I don't know about a steal, but definitely a reasonable price. The I-O-II-C is tough to find. The only reason it's not worth more is that there is currently a limited buyer's market for such an item. Nice find.
