On the low end; $300-$400 for a similar chest of drawers "without" that mirror. With that mirror, I'd say add another $75-$100. So, as is; $375-$500 on the low end.
If it was a new, modern piece for sale in a furniture store? Probably $900-$1,300. Expect to pay high prices for modern furniture, if it is well made and looks nice.
