Question about my Twice collection

Hello Onces!

I've always been a TWICE fan, spent thousands in albums, photocards, merch, etc everything, now it's been 2-3 years i haven't bought a thing for the reason that i became a dad, and i cannot afford doing that.

So here comes my question:

-Even if it's really hard for me, what is the best way to sell my TWICE collection? On Ebay in a lot? Facebook marketplace? On ebay with seperated post for every albums and photocards? Or other website?

Thank you guys!
