Thank you very much! My father purchased 10 Cal Ripken Jr. Rookie cards (the 3 person ones, not the valuable traded series ones) before Ripken became as well known as he is. He was just never quite able to sell them for the right price, and they have since landed somewhere buried in a box. I didn’t realize just how much cards like your Robin Yount rookie card were worth, and the great price fluctuation! That is very interesting!
