I would never have sold any, so I only regret the loss of childhood memories. Mother always collected backwards. When Roosevelt dimes came out, she ignored silver Liberties and only collected new Roosevelts.
Probably a case of economics, since she could collect 10 of the dimes instead of just 1 Liberty dollar. Besides, she was probably like most people who looked up to him as such a great man. Obviously well liked to be elected 4 times.
