This brought up another thought for me. I have quite a few rare globes. One is a single,cracked, one known, others have one cracked back lenses. how much do you guys think that the value of the globe retains by having a cracked back lens vs none at all? This would only apply to rare globes. I also have a very rare globe with 2 cracked lenses that I paid very well for and dont regret for a minute as I may never find another.........Thooughts?
