not sure what a 52 mantle signed for would be these days and kinda scared to find out considering the recent and sudden price spikes...I passed on a blue flipped beater about 2 years ago for 10K and it's looking like it was a mistake.
i do have a 83' one singed. figured that'd hold me over til that magical day comes. plenty of 91 nationals around, but the 83 is slightly harder and it was an actual topps produced card, has the original back and i like that it's even slightly oc which mirrors the original :
