take it to antique shop. or maybe a pawn shop. A grandfather clock could ne worth a lot of cash
You might check online in your area, to see if there are any dealers or hobbyists, who might be interested. Good luck!!
I have a old Seth Thomas grandfather floor clock. The glass in the door is no longer there and i have not put the weights or pendulem back in. Im trying to sell it but i keep coming to a dead end. Any suggestions? I live in houston tx 77080
