Professor Magnolia specializes in Pokemon Dynamaxing, while Sonia specializes in the history of Galar
Over the last six months, my numbers look roughly as follows: $103,789.23 in gross spending (include cards, packs, shipping, fees, etc.) $112,172.46 in revenue across all platforms ~$21,000 in raw card/pack inventory (based on current market value) ~400 cards at third-party grading services with a declared value of approximately $50,000 (based on current market value and their anticipated grades) What blows my mind about this entire process is that there are sellers that dwarf these numbers in terms of sales and sophistication of operation
In short, Pokemon cards can be super valuable and they can be worth as little as a penny a card
You can use binders, boxes, or sleeves to keep your cards in good condition and easily accessible
