The T206 set is 520 cards, all PSA graded with an average grade of 4.4.

First thing I would do is go to VCP and search the T206 set with common backs. According to VCP, the set in a PSA 4 (based off most recent sales of 520 cards) is $267,820. Then I run the same search but in a PSA 5, which gives us $486,747, but we need to reduce that by $119k to attribute for the Plank, so the revised PSA 5 value would be about $367k.

Considering things are moving so fast, making a number of VCP comps no longer accurate, I would tend to lean more to the PSA 5 set value in VCP, even though the average grade is 4.4.

Next I would look at the grades of the key cards and adjust accordingly (the Green Cobb is a 3, the red a 5, the batting a 3.5 and the bat on a 3, with the Cy Youngs in a 5, 4.5, 4, the Johnsons in 5s, etc). Bottom line, I do not think the HOFers are generally 5's and probably average closer to a 4, especially with two main Cobbs be a 3 and 3.5, respectively. So I would probably doc the value about $30k, getting me to a rough value of about $340k.

Then, of course, there is some value to being able to buy a complete, 520 card set, already all graded by PSA and currently on the registry, and I think this value offsets the downward adjustment just made because of the HOFers.

Thus, I would roughly put the value of the set at $370k -- at least that's the over/under and I would expect it will sell within 10% (above or below) of that amount, so $330k - $400k.

The set is at $319k, including buyer's premium, at the time of this post.

BTW - In July of 2020, I bought a 513-card registry set with an average grade of 5.76, albeit missing a few key HOF cards, like a green cobb and cobb bat on, for $310k, all in. I see that comp as supporting the conclusion that the Mile High set will likely fall within the range set forth above, maybe on the higher end.

BTW +1 -- The Mile High T206 set is totally awesome and whoever gets it should be totally psyched. It will be worth double in 5 years. Grading fees on that set alone is likely worth 10% of the final hammer price
