This is a Pyrex 3 piece stacking casserole set with lids that were made from 1966 to 1971. The pattern is called Early American and they are marked #473 - 1 quart (brown with gold); #474 - 1 1/2 Quarts (white with brown); and #475 - 2 1/2 quart (brown with gold). These look really nice but there is slight damage. The #474 white bowl has as small chips on the underside of one handle and the lid for the #473 bowl has some small nicks on the edge of the handle. I have tried to picture these so you can see.
