What a lovely dresser! I'm with the others that it looks to date to the late 19th century. Your aunt probably got it from her parents. If you look closely at those slotted screws, the slots aren't perfectly centered. That's a good thing. It's a sign of old screws, which had to be slotted one by one before they could be mass produced. This is really a neat dresser with lots of personality. I hope you will keep it in your family and treasure it, it's wonderful! The mirror looks to me like it is from a later set, maybe one of the "waterfall" dressers from the forties?
