antique buffet/server

this was given to my mother from a neighbor. i am guessing it is from the 1920s. but i really have no idea. i am interested in selling this as well as some other antique furniture but have no idea what the value would be.

it is 46 inches long and 32 inches high and is on wheels. has two drawers. it has some missing trim. the two top pulls are not originals and there is a small chunk of wood missing from the leg.

any help would be appreciated. thank you.
