Obviously, we look at prices all day, every day. We see some sales that appear to be dishonest on eBay. (I'm being nice)
There might be 20 finished auctions for a book and 1 is 30-50% higher than the others in the same condition. We've seen this happen on the same day before. We've seen raw books go for $100 or $200 more than a graded issue in the same condition. Does this kind of information interest you? I'm not sure how we could display or get this information to you but we are thinking about how to be transparent. Somehow tell you that we evaluated the data and statistically this sale doesn't make sense.
If a price guide used all automated data, some unscrupulous sellers could manipulate the market upward. Shill bidding on each other's books until they get the profit margin they want. Then every week report that it's a new high price because it's so hot. That news in turn, drives the price higher.
Think about this, stocks of great companies with huge profit margins rise and fall so why are comics continuing to skyrocket month after month with no decline? edited by ronbatman on 10/11/2021
