Mayer High-Relief Columbian Proof Liberty Medal with Box from the Kennel Collection #S408
John Kennel's extensive collection included FOUR proof Mayer medals and numerous non-proof high grade specimens.
In looking at the photos, you can see a slightly different shade of blue on the box. The photo with the lid closed and no medal showing (the lighter blue) is the accurate color, while the other showed up a bit too dark in the photo.
I have handled perhaps a dozen of these 35mm proofs and in 40+ years also have sold examples of the giant 90mm version of this medal--many years ago and in April 201,from the Kennel Collection of course.
No known proofs have been recorded for the 90mm size, but those cited above were all gem prooflike. Should a 90mm example show up in the near future I would be surprised if it sold for less than $1500. One did sell at auction in late 2021 for an unbelievable and unprecedented $3500. I don't know what effect that sale will have on the marketplace. These are so rare now that should another come to market in 2022 collectors anxious for an example might well push the price up to this lofty level.
The proofs we sold as part of the Kennel Collection were also quite varied as that's what collectors paid--from $450 to more than $1000 each.
