All these pieces are vaneered pieces from the 20's (possibly late 30's... The "oak" isn't really oak... It looks to have poplar sides which dates it to 20s-30s as opposed to the golden age of oak which was pre-WWI...
I hate to say it but none of these pieces are tremendously valuable and there are lots of this period stuff out there...
I doubt if an antique dealer would be intersted and furniture, unless it is high end antique, won't sell on ebay...
Find a collectables consignment shop and see what they charge to sell stuff... Most will get 30% to 40% of the selling price... The chest of drawers is about a $300 piece... Same with the vanity and mirror... Okay, maybe $350... I couldn't see the others too well but what I see of them they also fall into the 20's/30's vareered "Empire" style and are not rare...
BTW, the rounded legs of the "oak drsser" is "Empire" style as are the rounded balls on the legs of the other pieces...
Wish I had better news but I do know antiques... Grew up with 'um and am completely surrounded by them...
