I’ve done a few google searches, and I haven’t been able to find any sites/spreadsheets that give the expected value for the sealed product of various pokemon sets. Current values would be fine, but historical would be even better. Is anyone aware of such a resource?
Z&G Emporium has (had?) a site with the EV of all WotC boxes. Not sure if he still maintains it, though. The way he calculated EV was flawed, but it wasn’t terribly far off. Worth checking out.
I vaguely recall a similar thread for WOTC boxes, but am too lazy to look. As far as I know, no similar resource exists for more recent booster boxes, much less other sealed product like booster packs, tins, etc. Would be great if it did exist, though!
I just took a quick look, and his work looks great. If the calculations are flawed, then that is a shame, but better than nothing. Wish there was a resource covering all set to the present day too.
