9. Snowflake
Current ebay asking price: $275
Though the more geometric patterns eventually became the biggest sellers for Pyrex, Snowflake and Daisy were the first Pyrex patterns of their kind. Snowflake came in various colors, but the white on turquoise version ran all the way from 1956 to 1967 and was featured on casseroles and a divided baking dish. They were originally advertised as “New Pyrex Decorator Casseroles.”
