Brut 1928 Champagne - worth anything?

[meatball]

I have an old wicker basket/box with 5 of 6
6&1/2oz gold foil covered unopen bottles of PERINET & FILS Brut 1928 Champagne "CUVEE RESERVEE" produced and bottled in Reims, France. They are wrapped in stitched straw and neatly packed in grey felt paper with a small stick holding the box shut through two wicker eyelets. It's in great shape and a wonderful looking item. Is it worth anything and might it be drinkable? Thanks, Kent
