I've very familiar with the value of #1 I've owned three copies, currently have one as part of my final collection...7-8 years ago I remember #1 was a solid $100 book in VF/NM raw, I know because I sold one on ebay. It's been a gradual increase, and I'm not disagreeing with you but the price increase in this book over time has been much more organic and 'natural' then what we usually see in this thread. #44 for example, has spiked and fluctuated, but this book and other keys in the series have not seen any of the collectors going after them specifically like they did for TWD keys (like first gov, first michonne, ect.). You can't buy the whole run now for $300, but there was a time you could buy a huge run of it for $400-500 pretty easily...
