Where to sell antiques?

Hey everyone,

My grandpa is asking me to help him sell a vintage Red Wing crock. Shipping would be a major headache because it’s huge and fragile. Looking for ideas on how I should go about selling this?

I imagine most antique shops only allow vendors with a good amount of product. FB marketplace and eBay with local pickup are my only ideas so far but I don’t know how effective those will be.
