No offence but you come across as a novice picker. I have been a picker even before I graduated from college in 1963. In 1958 I purchased a 1916 Harley from a ladies basement, a few months later a 1930 Studebaker Roadster, all while I was going to college, married with three kids. I could go on with more examples, but basically you need to know more than just signs. Twenty-five years ago my wife and I became a team, I knew petro, automobiles, illustrators, magazines, calendars, my wife knew dolls, silverware, ceramics, dishware, jewelry, and many more subject I can't remember...but all this information was in our heads, we didn't need guides. There was hardly any auctions we went to where we didn't find something we could not make money with. We are also possibly teaching a course (Picking 101) at our local community college this fall.
All around you are things that are worth money, just don't go out there looking for signs, learn what that nozzle/pump/oil can/everything listed above/etc. is worth, make that trip to that auction/etc. pay for itself.
If you do buy guides, and that is a good idea, put them in the bathroom, there is where you will probably doing the most reading.
