3 Piece Dresser Vintage Set - United Furniture Corporation NC - What's it Worth?

I need to sell my bedroom furniture. I actually bought it off of Craigslist for $80 a couple of years ago. However, I noticed that is is from the United Furniture Corporation of North Carolina. When I started researching it, people said that they produced during the depression era.

The dresser is very sturdy and is in great condition structurally. However, it definitely needs to be refinished. There are a lot of scratches and markings. It is blonde wood and I noticed a 320 M stamp on the back of the pieces. There are three pieces (large dresser with mirror, smaller dresser, and nightstand). Any ideas on when this set was made? Is it valuable? Do you have any kind of price estimate? Thanks. Attachment 6371Attachment 6372Attachment 6373Attachment 6374
