Value of an antique bed frame

I have a bed frame left behind by the ex a few years ago when she moved out. It had been stored for years, and I’d like to get rid of it, but have not idea if its worth a great deal or very little.

Stuff I know -
The headboard looks to have a veneer on it.
Made by the Holland Furniture Company, which looks like a Michigan company in the early 20th century.
That’s about all I know.

Any ideas on how to find out more, what to look for, etc?
