Factors like age, item type, size, colors, and condition affect the value of carnival glass. Pieces dating before 1940 are more valuable, as are complete sets of items and larger objects. Colors like ice green (which is sold for over $16,000) and marigold are rarer and highly prized.

What colored glass is worth the most?

Pink glass is most valuable, followed by blue and green. Rare colors such as tangerine and lavender are also worth more than common colors like yellow and amber.
