Antique Hand Painted Cabinet with Mirror, Maybe Louis XVI Style

This cabinet has been in my husband’s family for a few generations, his mother remembers it from her grandmother’s farm near Louisville, KY. It has no identifying markings, but is wood, with one interior shelf, green and gold/yellow, with a heavy carved wooden mirror with painting along the top. There is damage along the bottom of the cabinet and the wood at the top of the mirror broke during a move, but I have the pieces. We are wondering about the value and whether it should be appraised properly for insurance.
