Absolutely FINANCIAL ADVICE!
While all attention is directed towards Pokemon's 30th set, we have tunnel vision. In the way that is allowing ourselves to miss massive deals out there. If you are looking to build your sealed collection, let me direct your attention to opportunity that I believe won't last that long.
The very first thing that catches my eye is Perfect Order Booster boxes sitting at MSRP. At this very moment you can purchase one practically anywhere, for around $160-$170. This set doesn't have the all the big name pokemon that bring attention to a set. BUT it has cards that will age extremely well. Cards that just get overlooked due to everything else before this set and after it.
The next set I notice is Battle Styles sitting under $300. You can pick one up around the $280 mark. Any Sword and Shield set should not be under $400 minimum! I don't think this lasts much longer and once attention goes back to everything other than the 30th collection we will start to see momentum on era's that are NO LONGER BEING PRINTED. There will never be anymore of these leaving the printing factory. This is the only booster box under three hundred from this era.
Next I would like to point your attention to one of the earlier sets out of the Scarlet and Violet era, Paradox Rift. Probably not the sexiest booster box to pick up, but thats partly the point here. Sealed collecting works best when you are buying the set people aren't currently obsessing over. Sitting at about $275 a box this seems like a no brainer if you are trying to build your sealed position.
Lastly I want to talk about Journey Together. A set everyone watches, waiting for a good opportunity. Everyone knows this one is a great deal at $225 for a booster box, but never pick it up because something new coming out every other month and the hype train is leading you further and further away from a great opportunity. It's a very unique set and just deserves to break the $275-$300 mark in the near future.
Take what you want from this information. Happy collecting.
