Many good comments here. I have watched this hobby for 40 years now. This topic comes up all the time. In a nutshell, prices adjust up and down but the only major adjustment I had ever seen in this hobby was around 2007-2008 when prices on certain items got way too high, the economy took a dump and gas and oil followed in some areas. Prices have since mostly rebounded, some now beyond that. I sell many gas globes in the $250-$1000, which are staples items for me. Rare and expensive ones have a limited market but when you can find them they sell. American Pickers have brought awareness to what we all have been doing for years but in my opinion have down more harm than good to our hobby. As I've stated for decades, that fact that gas and oil is so closely tied to the automotive markets I feel it will always remain strong. Scott B.
