I had a huge run of TWD I listed on ebay by auction last month. This is something I would almost never do, but I wanted to get it sold and shipped before I took off on a trip (this was from a large collection of 10k comics purchased a few months ago, I continue to sort through this large collection but wanted to get some money back very quickly). The results were so %*&$@ I'm too embarrassed to post them here, but at the end of the day they're out of the house. What my auction told me is that these TWD comics, especially big runs and especially when you get past issue 20, is quickly on the decline in demand. If you want to sell your collection, or any TWD books, don't wait any longer to do so! #1 will always be valuable, but I sense a slow gradual decline in price before it bottoms out somewhere.....
