Lg church chair

This chair is 52in in height 24.5in at the widest part of the seat and 21.5in deep. The seat and back part are dark brown and a very durable material (possibly leather). I'm not sure what type of wood it is but it is extremely heavy.  It has 9 heavy duty springs underneath wrapped in a thick burlap type material. I got it from an old church. I have another one that is identical in every way except the height which is 56.5in.  I haven't a clue how old or what they are worth. Although, I love the way they look in my living room,  I would  love the way some extra $$$ would look in my checking account even more.  Lol  from what I understand there are details about the way furniture is put together that helps to identify its age so I have included photos on the bottom of the chair.  If anyone has any idea how old they are, what they are worth, or any comments I would appreciate hearing from you. I can be contacted directed  at [email protected].
