Question Re 1959 Topps Warren Spahn "Born In 1931" ...

This auction for a 1959 Topps Warren Spahn PSA 7 "Born In 1931" sold for $444.00. SMR on a "regular" PSA 7 is all of ... $60.00. According to Baseball Reference, Spahn was born in 1921, so guess this is an error card. Is this card that rare to warrant the huge premium? Just curious.

1) the POPs for all 3 variations are extremely similar... which is ODD!
2) a PSA 8 on June 26th sold for less.
3) Power of the PSA Registry!
