Experts say that the company’s Wonderlier and Servalier lines are particularly collectable, with full collections in high demand by dealers.
The Servalier range is the one many of us would recognise from our childhoods - with the colour range varying from bright orange to avocado green and bright yellow.
The Wonderlier bowls - in pastel colours - were in many of our homes growing up, as were the ‘Startburst’ canister range, which feature a star motif on the front.
Experts say the 1950’s ‘Millionaire’ range of pale pinks, greens, and blues are still highly sought after, too.
The most valuable sets are ones where all the cannisters and lids are complete and still fit. Tupperware expert and collector Stacy Verdick Case goes on to say that the most popular Tupperware comes in the “Crystal” colour, as the company still makes replacement lids in that hue.
But before you start looking to sell - or buy! - any vintage Tupperware, it’s important to check whether it’s authentic - which expert Stacy says is a simple process.
‘To authenticate any piece of Tupperware, look for a two-part number (its mould number) stamped somewhere on the product and make sure the word "Tupperware" is also visible,’ she says.
The 'Wonderlier' Tupperware bowls (above) are hugely collectable now - do you have some in your old cupboards?!
