Most carnival glass sells for approximately $20-60 a piece. It is pressed glass with a shimmering, oil on water surface, made in huge quantities in the United States from about 1908 into the 1920s by Fenton, Northwood, Imperial, Dugan and a few smaller firms. The common pieces, especially marigold bowls in familiar patterns, turn up at every estate sale. What lifts a piece into the hundreds or thousands is the combination of maker, pattern and base color: Northwood Peacock at the Fountain in a rare color, Millersburg pieces, Fenton red, and the pale ice blue, ice green and aqua opalescent colors. Reproductions and later reissues by Fenton, Imperial and others are common and worth much less. Chips, cracks and worn iridescence lower value sharply.
Quick answer
- Most carnival glass, especially marigold bowls and vases, sells for $20-60.
- Value comes from maker, pattern and base color. Red, ice blue, ice green, aqua opalescent and rare Millersburg pieces are worth far more.
- Later reissues, often marked by Fenton or Imperial, and chipped or worn pieces sell for less.
How to check yours, step by step
- Hold it up to a light. Look through the glass, not at the surface, with a window or a phone flashlight behind it. The color of the glass itself, called the base color, is how collectors name carnival colors. Marigold is clear glass with an orange iridescence. Amethyst looks purple through the light, even if the surface looks black.
- Look for a mark. Turn the piece over and check the center of the base, and on bowls the inside center as well. A capital N in a circle, or an underlined N, is a Northwood mark. A script Fenton logo in an oval, the letters IG, or LG marks usually mean a later reissue, not original early production.
- Identify the pattern. Look at the main design, inside and out. Note the motif (grapes, peacocks, stags, orange trees, holly) and the shape of the piece: bowl, plate, vase, pitcher, tumbler, compote. Many patterns were made by one maker only, which identifies it for you.
- Check the back pattern. Bowls often carry a different design on the outside, such as a basketweave, a wide panel or a ribbed pattern. The combination of inside and outside patterns helps identify the maker.
- Look at the iridescence. Tilt the piece under daylight. Strong, even iridescence with blues, golds and purples across the whole surface adds value. Thin, patchy or worn iridescence lowers it.
- Run a finger around the edges. Feel the rim, the points of a ruffled edge and the collar base for chips and flakes. Look for cracks by shining light through at an angle.
- Measure it. Note the diameter of a bowl or the height of a vase. Some patterns are worth much more in particular sizes or shapes, such as a plate rather than a bowl.
The main makers
| Maker | Years of carnival production | Identifying clues | Notes |
|---|---|---|---|
| Fenton | From about 1907, with later reissues from about 1970 | Unmarked on early pieces; script Fenton logo in an oval on reissues | The largest early maker; known for Orange Tree, Stag and Holly, and red |
| Northwood | About 1908 to the mid 1920s | N in a circle or an underlined N, often in the center of bowls | Grape and Cable, Peacock at the Fountain, Good Luck, aqua opalescent |
| Imperial | About 1910 to the 1920s, reissues from the 1960s | Early pieces unmarked; IG mark on many reissues | Strong marigold and smoke; Imperial Grape |
| Dugan and Diamond | About 1909 to 1931 | Unmarked, identified by pattern | Good peach opalescent and amethyst |
| Millersburg | About 1909 to 1912 | Unmarked, identified by pattern | Short production, high quality, collectors pay strong prices |
Other American makers include Westmoreland, Cambridge, Jeannette, Jenkins and US Glass, and there is a large market in European and Australian carnival glass from firms such as Sowerby, Brockwitz, Riihimaki and Crystal Glass. Later, lighter carnival made in the 1920s and 1930s, sometimes called depression carnival, overlaps with the glass in our guide to depression glass.
Colors and why they matter
Color is the biggest single price driver after the pattern. The early makers produced marigold in vast amounts because the clear base glass was cheap and the orange finish sold well. Other base colors were made in smaller runs, and the pastel and opalescent colors in the smallest.
| Base color | How it looks through light | Relative rarity | Typical value for a common pattern bowl |
|---|---|---|---|
| Marigold | Clear glass, orange gold surface | Very common | $20-60 |
| Amethyst and purple | Purple through light, dark surface | Common | $40-150 |
| Green | Green glass | Fairly common | $40-150 |
| Cobalt blue | Deep blue glass | Fairly common | $50-200 |
| Peach opalescent | Marigold surface with milky white edges | Less common | $50-200 |
| White | Frosted, pale surface | Scarce | $75-300 |
| Ice blue, ice green | Pale tinted glass with a frosty finish | Scarce | $150-1,000 |
| Red | True red glass, mostly Fenton in the 1920s | Rare | $300-2,000 |
| Aqua opalescent | Pale blue green with a milky edge, mostly Northwood | Rare | $500 to several thousand |
Some colors fool people. Black looking glass is often amethyst, and a smoky or grey surface can hide clear glass. The light test settles it. Rare colors also attract fakes and reissues, so a red or aqua piece needs a close look at the maker marks.
Patterns collectors want
| Pattern | Maker | What to know | Typical value |
|---|---|---|---|
| Grape and Cable | Northwood, also Fenton | One of the most common patterns; huge range of shapes | $30-100 for marigold bowls, much more for rare colors and large pieces such as punch sets |
| Peacock at the Fountain | Northwood | Peacock on a fountain, on berry sets, punch sets and pitchers | $75-400 common colors, far more in aqua opalescent or ice blue |
| Peacocks on the Fence | Northwood | Peacocks on a fence, mostly bowls and plates | $100-500 |
| Good Luck | Northwood | Horseshoe and riding crop | $100-500 |
| Orange Tree | Fenton | Very common; many shapes | $25-100 |
| Stag and Holly | Fenton | Stags and holly, footed bowls | $50-300 |
| Imperial Grape | Imperial | Frequently reissued | $20-80 for originals |
| Millersburg patterns (Peacock, Hobstar and Feather) | Millersburg | Short run, high demand | $200 to several thousand |
Plates of a pattern are usually worth more than bowls, and full water sets and punch sets more than single pieces. Tumblers in common patterns sell for $10-40 each.
Reproductions and later reissues
Carnival glass was revived in the 1960s and 1970s. Imperial reissued many of its own patterns, often marked IG. Fenton reissued carnival from about 1970 until the company stopped making glass in 2011, usually with its script logo. Other firms, including L.G. Wright, Summit, Boyd and Mosser, produced copies of early patterns, sometimes from old molds. Some reproductions carry a fake or altered Northwood N.
Signs a piece is later:
- A Fenton, IG or other modern maker mark.
- Colors that were not used in the early period, or very bright, even iridescence that looks sprayed on.
- A shape or pattern that the early makers never produced in that color.
- Sharp, crisp mold detail with no wear on the base where a hundred year old piece should show scratches.
- A slick, heavy feel with thick base glass.
Later pieces are not worthless. Many Fenton and Imperial reissues sell for $15-60, and some limited Fenton editions have their own collectors. They are simply a different and cheaper market than the early glass.
Condition
Condition changes carnival values more than people expect.
- Chips and flakes on the rim, ruffle points or collar base cut value by a third to a half on common pieces.
- Cracks reduce most pieces to a fraction of value.
- Worn iridescence, especially in the center of bowls where spoons and fruit rubbed, lowers value.
- Weak or patchy iridescence from the factory is common on some makers and also reduces the price.
- Cloudy interiors on pitchers and vases, from mineral deposits, are hard to remove and lower value.
Do not put carnival glass in a dishwasher. The iridescent layer is on the surface and can be worn or dulled.
Common mistakes
- Assuming all iridescent glass is old carnival. Much of it is later reissue or modern decorative glass.
- Naming the color from the surface. Collectors name the base color seen through light.
- Trusting the N mark alone. Some reproductions copy it.
- Valuing a marigold bowl like a rare color. Marigold is the most common color by far.
- Ignoring small chips on ruffle points. They count.
- Cleaning with abrasive pads or a dishwasher. It wears the iridescence.
- Relying on asking prices online. Many listings never sell; check sold results.
What to photograph
- The piece from the side and from above in daylight, showing the full pattern.
- The piece held up to a window or with a flashlight behind it, to show the base color.
- The base, with any mark sharp and readable.
- The outside or back pattern of a bowl.
- The rim and base edge close up, showing any chips.
- A ruler or tape measure next to the piece for size.
When to get it looked at in person
- An antique dealer familiar with American glass can identify maker, pattern and color in a few minutes and give a realistic price. A good first step for a mixed box.
- A carnival glass collectors club is a reliable place to check rare colors and patterns. Members know the reissues and the true rarities and are usually happy to help with identification.
- An auction house with a glass department, or one of the specialist carnival glass auction firms, is the right call for anything you think is red, aqua opalescent, ice blue or Millersburg. Estimates are usually given at no upfront cost.
- An appraiser charges roughly $50-150 an hour and is only worth it for a large collection, insurance or an estate division.
