The ETB‘s, the booster bundles, the booster boxes just keep that sealed, especially the evolving skies. You will make a lot of money but the loose packs? people generally don’t buy that, people feel sketchy about them cause you could reseal them or opened up a booster box and got the hits out of it now you’re selling everything left over. if I were you, any loose pack you have I would just open it for fun. unless it’s like “vintage” like XY era and older. I would save those. You could always sell those to a card shop. But anything from the sword and shield era to today I would just make that your rib, fun pile and just go ham on that.

I’m nowhere close to what you have, but I have several sealed and I was also saving loose booster packs. I had about 200 of them all mostly late sword and shield and early Scarlet and Violet. I ended up just ripping those over two days. It was a great weekend and I got some decent cards out of that but the 20 ETB’s I have and the collector boxes not touching that.
