What a great thread, awesome explanations @hyruleguardian! I´m not even looking for a 1st Ed. Base Booster but for 2.5-3k I would even buy one. So I guess the value is much greater than that.
To add a bit to the discussion, the value of a sealed booster pack is only very loosely related to its possible contents and their value. There is buyers for light unlimited jungle packs at 50$ when the content is literally worth pennies.
1st Ed. Base being THE set, a sealed confirmed heavy pack is almost priceless given the scarcity of the item.
Heavy boosters I watched over the course of the last year of “normal” WotC sets tend to be around 1/10-1/14 of the value of a sealed box, not including exceptions like 1st Ed Base. That by itself is pretty ridicolous as you can just break boxes endlessly, maybe another reason why boxes also drastically increased in value recently.
haha, i would love to get my hands on a set of heavy 1st ed packs, one of each art. 10k for 3 doesn’t sound too bad considering they do have the sought after holos, potentially a psa 10 charizard, blastoise, chansey, hitmonchan… big cards.
Worst case assuming that the variance in the extra packaging is larger than the difference between light and heavy packs they would still be weighable to some extent.
E.g.
Say a heavy pack weighs 25.0 grams and a light pack 24.0 grams (made up numbers). If the extra packaging weighs somewhere between 2-4 grams (made up numbers) then you have a scenario where the worst case I mentioned above is true (variance in packaging weight is higher than heavy’light difference). Well you’ll still be sure that any ~26.0 gram packs are light and any ~29.0 gram packs are heavy. Anything in between 27-28 will be harder to say, but still on average heavier packs will contain a higher than 1:3 rate of holos. The higher the packaging variance the harder it gets, but technically you could always tell when a light pack aligns with light packing or a heavy pack aligning with heavy packing.
I’ve never confirmed it myself, but recall hearing some time ago that the variance isn’t nearly that high though and blisters can be fairly reliably weighed.
