A snapshot of recent eBay sold prices for vintage iridescent carnival glass (1908-1925) — Northwood, Fenton, Millersburg, Imperial, Dugan — and the color premiums that drive the high end of the market.

Carnival glass has the widest pricing spread of any vintage glass category — the same pattern can sell for $30 in marigold and $3,000+ in a rare color. Color dominates everything else; pattern and maker come second. A piece with the wrong color in a great pattern sells like a common piece, while a piece in red or ice blue in any pattern commands real attention.
Red: Rarest. Required cadmium, expensive to produce. Confirmed red carnival pieces routinely fetch $1,000-$5,000+ in rare patterns. Ice blue, ice green, white: Pale frosty iridescence variants — production was limited and supply is thin. $200-$1,500 ranges. Amethyst, peach opalescent: Mid-tier rare colors, $80-$400. Marigold: Most common, the entry color, $25-$200 for most pieces. Beware: many "rare colors" in seller listings are exaggerated — true red and true ice colors are uncommon enough that experienced collectors can spot the difference from photos.
Millersburg sits at the top — only operated 1909-1911, produced limited quantities, and many pieces are unique survivors. Northwood is second, marked with the N-in-circle from 1908 forward, with extensive pattern catalogs. Fenton is the largest single producer and the most plentiful maker in the market. Dugan/Diamond and Imperial round out the major makers. Unattributed pieces sell for less; pattern guides help with attribution from photos.
Iridescent finish is fragile — scratches, "haze" from improper cleaning, and wear from stacking dramatically reduce value. The bottom and base ring see most wear. A piece with bright complete iridescence sells for 2-4x the same piece with surface wear or haze. Original "frit" (the iridescent metallic spray) cannot be restored — once it's worn, the piece is permanently devalued.
Carnival glass collecting is a dedicated specialist market — major collectors are concentrated in the Pennsylvania, Ohio, Indiana corridor and pockets of the South and Midwest. eBay is the primary national venue. Carnival glass societies (the American Carnival Glass Association, the International Carnival Glass Association) run annual conventions and auctions where high-end pieces change hands at prices well above eBay norms. Estate sales in the original production corridor occasionally surface significant pieces priced as common ware.

Red is the rarest and most valuable carnival glass color — production was limited because red glass required cadmium and was expensive to produce. Confirmed red carnival pieces can sell for $1,000-$10,000+ in rare patterns. Ice blue and ice green follow (both unusual variants with a pale frosty iridescence). White carnival is rarer than commonly thought and commands premium. Marigold, the most common color, sits at the bottom of the price range but is the entry point for most collectors.
Northwood pieces from 1908 forward carry the N-in-circle mark on the base — the most reliable maker identification in carnival glass. Fenton rarely marked their carnival pieces during the original production era (1907-1920), so Fenton attribution is by pattern. Pattern guides (Hartung, Edwards, Carwile) are the standard reference. Visual differences: Northwood's iridescent finish tends to be more saturated and slightly thicker; Fenton's is often finer and more variable. Imperial carnival also carries an embossed mark (cross-shape inside a circle).
Modern carnival reproductions (1970s-2000s) from Fenton, Imperial reissues, and import producers have collector value but at a fraction of original 1908-1925 pieces. A modern Fenton carnival piece typically sells for $20-$80 depending on size and pattern; a comparable original Fenton piece in marigold from 1910 sells for $80-$300. The reproductions are honestly marked (Fenton's oval-F mark, Imperial's IG mark, etc.) so identification is straightforward. Look for the period production marks before paying period prices.
