Is Powerful Angry Gordon Really this Rare?

hello everyone & thank you for the warm welcome. I recognize some names here. I hope I'm not too out of my league. I am always amazed at the description "rare". It seems to be applied to frequently. In my opinion "rare" has to meet certain criteria. #1 never seen for sale but in existence. #2 never seen and might be in existence.#3 seen once or twice a year and in existence. after that its just hard to find...if that.
