1700's Ladies Writing Desk

 I received this desk after my Mom's passing.  She collected alot of antqiues and especially Irish antiques.  She told me that this desk was a 1700's Ladies Writing Desk.  I have no idea about antiques and don't know if this is what she thought or how much it is worth. I can provide more pictures and look for more details on the desk if that helps anyone. Could someone please point me in the right direction and give me an idea of how much this desk is worth?  Thank you.
