What affects the value of Tupperware Sandwich Keeper?

• The presence of the original light brown lid, as mismatched sets significantly decrease the $12-$15 market value.
• Clarity and legibility of the Tupperware maker's marks on the base of the polyethylene container.
• Overall color vibrancy, as sun-fading on the red base can impact the desirability for mid-century collectors.
