As of 2016, vintage-Tupperware collectors consider particular complete sets of Tupperware valuable, such as the nesting bowls from the 1940s to the 1960s, paying up to $45 for a set that is in good condition, according to CountryLiving.com. The majority of single vintage Tupperware pieces are not very valuable.
Crystal and white are the most common vintage Tupperware colors. Pink vintage Tupperware is more valuable, as it is harder to find since most pink vintage Tupperware pieces have faded to white over time. Vintage Tupperware is sold at many flea markets. Some sellers on Etsy.com and eBay.com offer vintage Tupperware sets from the 1940s to the 1980s.
