Here are 2 auctions for that book that seem way over priced:

I'm not sure about there only being 200 of these as this was an incentive where if you ordered 200 of the regular issue you got one of these. I know that DDP did not have this advertised anywhere so it caught everyone off guard and most people don't actually know it exists.
The other books you have mentioned are all very recent books and garnered a lot of attention amongst Joe fans. There are enough of them around that all the serious fans were able to get copies. Elite 11b is much lesser known, is an incentive on a regular unremarkable issue, has one of the coolest covers of the series, it has entered into collecting lore for these reasons.
If anybody has further info on this issue please let us know!
