Sorry, but as others have said, a lot of the data points you’re using are extremely inaccurate.
For example, the Charizard auction that’s being referred to happened in 2019, but also was for a Charizard that had a cracked case. That Charizard had to be re-submitted to PSA to fix the case and in such circumstances PSA does not guarantee the card will remain the same grade.
A more accurate estimate is the $72k BGS 9.5 Zard with 2 10 sub-grades that recently sold. I also know of a PSA 10 1st ed Zard that sold privately for months ago at an evaluation of $75k. I’ve seen offers of $60k for one and these people have not been able to find any sellers.
Chansey is also woefully underpriced, while Blastoise is overpriced.
Also like… you didn’t even include either the Red Cheeks or Yellow Cheeks Pikachu in your OP, which combined sold for over $3.5k for most recent sales.
Among many other flaws in your estimates.
Here are more realistic estimates in the current market:
Alakazam - $5-6k
Blastoise - $12-15k (E4 current offer of $14k and hasn’t been able to find any sellers)
Chansey - $13k-15k
Charizard - $60-75k
Clefairy - $5-6k
Gyarados - ~$5k
Hitmonchan - $7-10k
Machamp - ~$4k
Magneton - ~$6k
Mewtwo - $6-7k
Nidoking - ~$4k
Ninetales - $6-7k
Poliwrath - $3-4k
Raichu - ~$6k
Venusaur - $7-8k
Zapdos - ~$5k
I’d estimate around $25-30k for the non-holos although I would really need to comb through more data to be more precise.
Keep in mind this is just a snapshot in time, and prices can be very different tomorrow (if they’re not already).
Taking the average of all of these estimates, it adds up to $182k. Of course, take all of these estimates with a grain of salt, because they’re just estimates. I went slightly more conservatively in my estimates than simply last sold price - like Jeremy did, which is why his estimates have the set at over $200k
This is just the reality of where we are now based on sales we have seen in recent months.
Having said that, if a complete set went on auction today, I highly doubt it would get as much as what the individual cards add up to. There are many reasons for this. But the bottom line is that if you’re a seller, you’re insane to try to sell it as a complete set when the individual parts add up to so much more. (On the other hand, if you can find someone crazy enough to sell you a complete set at a discount, go for it)
