Like many, I have quite a few collecting-related regrets, but the one that bugs me the most is selling off my copy of Flintstones: Surprise at Dinosaur Peak back in 2004. It was one of those perfect collecting moments; I found it at a thrift shop for literally a few bucks. Unfortunately, I needed money badly since I had just lost my job and ended up selling it on eBay for around $60.00 (which was actually the going rate at the time). Needless to say, looking at current prices, the end result was bad for me
