I beg to differ, there are hobbies and hobbies, people have different intensity, its nice to have information to cover those intensity levels but don't expect everyone to be die hard in whatever they collect, I don't read books on funko pops but I collect them, same with metal detecting, silver coins in general, im allowed to be a collector and just advance my knowledge organically rather then drag my rear to every library or drop thousands of dollars on reading material before buying my first Indian head.
