6. New Dots
Current ebay asking price: $300
Sometimes known just as Dots, this mixing bowl set featured bowls with three rows of dots in varying sizes, most commonly in yellow, orange, blue, green, and orange. One of the most popular Pyrex patterns of all time, it was produced from 1969 to 1973. Single bowls are fairly easy to come by, but a complete set can set you back quite a bit.
