Best way to offload rares $1.50 and under?

Hey Finance Wizards,

Just looking for advice on how to liquidate maybe 15yrs worth of rares that I’ve always kept “just incase”. Came to a conclusion with my friends that when building new decks, we all will just add a card to cart if it’s under $2 instead of digging to find it so this anthology of rares is largely useless now.

I’ve unsleeved 60% of it already and started scanning it into ManaBox because there are definitely hidden gems in there that I didn’t expect to be of any value so seems worth the time to at least scan one copy of each rare for some found money.

There are some SCGCons coming up with plenty of vendors to entertain my collection. Just wondering if anyone has experience in getting good value from their bulk rares and how to do it with the best pay out and efficiency! Any vendor specifically that you’d recommend and their process? Any sites that are good?

I have used cardkingdom before and probably will sell the higher things that way but going through 15yrs of cards and buy listing things for $0.20 at a time isn’t time I have to spend.

Thanks for reading!
