Selling items on eBay

Hi Reddit readers, I’m looking for some insight on beginning to sell items from my childhood home 🏠 on eBay. I’m a first time eBay user. Would anyone happen to know what VHS Disney tapes (some almost like new in the plastic case) would be worth? Or a Cartman from Southpark doll still in its package? Or Barbies still in boxes? Beanie babies? My sister got divorced 12 years ago & she has a beautiful set of Lenox china (never used) that I am able to sell. Any suggestions or insight would be greatly appreciated! Thanks 😊! 🫶🏼💗
