chair and game table

These pieces belonged to my ex-husbands grandmother.  He wants to sell them and we have no idea of the value.  When I asked him what he knows about them he said, "Well, gramma said they are really, really old."  

The pieces are in great shape except for the fact that he seems to have misplaced the chair backs.... ouch!!  My best guess is they are Savonarola but I get confused once I try to identify a correct era.  The arms have the lion head (or leopard head?) but the feet are not decorative.  

Any information is appreciated and I would love to get my estimated price range narrowed down.  My research has produced retail results for similar items from $250-$600 for the table and anywhere from $300 per chair to $2800 per chair.  please help!!  Thank you for your time
