Widdicomb mahogany dresser and chest

Vincent oil painting of the woman laying down

Found this in my attic. Have tried researching and can't find a similar one. 

stamps unknown value

Old dresser still in good shape 5 drawers, jus wondering if it's worth anything, I was told it might be. 

A friend really wants to know the value of the silver coins. Anything will be immensely appreciated because locally he was offered below spot price of the silver value, when they're well aged.
