Thought this was interesting. Feel free to draw your own conclusions. But I did a simple tally of the listed population of Mantle Cards according to PSA (I excluded qualifiers).
A few things that jump out to me:
-The '69 White letter variation is exceedingly rare compared to other Mantle's. As of this moment, there are zero auctions on eBay.
-Pretty sure PSA didn't label '56 white/gray backs until very late in the game hence the seemingly low pop of '56 whites. While I agree a white back '56 is tougher than a gray back, I don't think the current ratio of white:gray in the population is an accurate reflection of the true population.
-'65s are much less plentiful than other '60s issues. It was from a later series so maybe that's it?
-Big drop off in population pre-'56.
What jumps out at you?
