Cool stuff. Really cool stuff. Wish I had one.
The answers are essentially that they are scarce and the player was great and demand is high. I guess what I was getting at is why has demand always been high for some cards. I know it's not easy to answer. I have somethings in my collection where they are amazing hall of famers and less than 10 of them have been graded and there is little or no demand for the card. Some Zach Wheat strip cards as one example. Some of them I probably couldn't sell for $250. At some point there is a collective decision by a mass of people that the card is rare and a great player and is aesthetically pleasing. Like the 52 Mantle. I think there is a very subjective aspect to the demand for certain cards. Not saying it's good or bad. Some cards just have that "it" factor. Someone above said "he looks like a ball player". Maybe that's about it.
