1951 Bowman Mantle vs Mays
Has anyone the data to show how these 2 cards compare over the years ? I recently went to the PSA site and the average of these 2 cards in Grade 7 were (Mantle $ 30,866) and Mays ( $12,731). Has this been the ratio over the years 2.5 x value ? Seems the Mays is underpriced to me, any comments.
