I started selling comics full-time in 2010 and wanted to track my progress against the online back issue markets. Here's a look at the current comics aftermarket and my progress in achieving my goal of becoming a prominent back issue dealer.
eBay's reported number of listings is now removing suppressed listings and I'm now unable to find a way to add those back in to their total so from now on we're going to go with their reported number. I know they are suppressing listings from this number because a prominent comic dealer (NK) had their reported figure drop substantially. They are known for listing multiple copies of the same book in a lot of different grades. A search in their store for Action 687 returns four results but, there is a small notation in their eBay store that they actually have 48 results for that search. I do not see a way to display all 48 results, though. Naturally, with a different method of calculating their number of listings now being used, our numbers are going to show some major swings over previous dates. Eventually, this will normalize. Atomic Avenue: The number of listings on this marketplace increased by 50% of the past month. That's an incredible increase - almost impossibly so. To make things even more odd, the number of unique available issues only increased by 0.57%. It'll be interesting, next month, to see how many total listings they have. Comic Collector Live: The number of stores has dropped by over 33.33% in the past five years. HipComic's number of listings have increased by over 100% in the past year.
