Consider where you get your information from and how it may influence your feelings/thoughts on certain cards. Those who hype niche Charizard cards on Instagram, WhatNot, etc. may not represent the general collector consensus. Similarly, e4 may not reflect what people buy/want on IG, WhatNot, etc.
Getting a pulse on the card from a wide range of collectors is crucial, as influencer advertising and hype can cause FOMO and misconstrue the true value of low pop cards. If you want evidence of how advertising and FOMO can balloon prices of low pop cards, look no further than modern BGS Black Labels. Once the first few Black Labels sell for sky high prices (e.g., PWCC auctions of Moonbreon, Poncho Pikachus), follow-up auctions and BINs tend to fall off to a reasonable price.
At the end of the day, a low pop card will sell for what someone is willing to pay for it. If you want to spend $10,000, $20,000, $30,000+ on the card, nobody is going to stop you. I’m not going to comment much on your hyperbolic statements of its desirability and rarity. We don’t know its desirability or rarity because they haven’t sold regularly in auction and PSA has only recently begun to add the correct labels.
If I were to put myself in the shoes of a Charizard collector who loves low pop cards and errors, I would price it at no more than 2x the PSA 10 going price. This would be between $7,000-$10,000. Beyond $10,000 would be insane in my opinion. Could it reach beyond $10,000 in auction? Perhaps. Will it sustainably sit there? Who knows. I would bet not.
