So sorry for the loss of your mother !! Ethan Allen is a good brand of furniture but these pieces may be difficult to sell except in a specialized market !! Its saving grace is that most will go well in a retro, modern or minimalist setting !! Its downfall is that its wood when many are going to painted surfaces !! I can tell you approx what it would bring in my area but it could bring more or less where you are located !!
Dining table and hutch sold together approx. $450. TO $500. It has good clean lines and table can be expanded to seat a number of people !!
Drop leaf bar,,approx $75.
End tables,,approx $30. to $40. ea. I would say closer to 30 since it has more traditional pulls !!
Chest,,$100 to $125.
Dresser,,$75 to $100
Small storage cabinet $35. good thing is it can be used for video storage or a sewing cabinet ect !!
Clock is quite traditional and could be harder to sell but a fair price,, if its Ethan Allen too is about $300. !! Other brands could be more !!
