Northwood carnival glass — pressed glass with an iridescent metallic-salt finish — is a major collecting area, and its underlined N-in-circle mark helps confirm the maker. Common colors like marigold in ordinary patterns sell for about $30–$150, but scarce colors are where the money is: ice-blue, aqua opalescent and rare patterns reach the hundreds to low thousands, and truly rare examples have sold for far more at specialist auctions. Value depends on color rarity, pattern, and how crisp the molding and iridescence are — wear to the radium finish or weak molding lowers price. It's a market where the specific color-plus-pattern combination decides everything.

Typical sold price ranges
Prices swing hugely by color-plus-pattern; the high end is for scarce colors like ice-blue and aqua opalescent, not common marigold.
