HA! Was just thinking about the ComicCoin debacle jus the other day. It was slightly before my time but I believe it went something like this: Everyone would put in some money to buy a book, let's say Spiderman 20 CGC 9.8 for this example, The book costs 15 grand let's say. 15 people would put up 1 grand each and they would all technically own the book together. One person (the grand wizard who dreamed up the abortion of Comiccoin) would have the book and issue everyone a coin that would be a percentage of the ownership of the book. So you would say, "I own 10% of such and such book while only owning a neat looking Comiccoin." while ComicCoin wizard would have the actual book.
Yes, it was that stupid.
