Most vintage jadeite glass sells for about $10-35 a piece as of late 2026. Fire-King Jane Ray cups and saucers, Restaurant Ware plates, mugs and small bowls are the common pieces, and a single cup and saucer typically sells for about $15-30. Larger and scarcer pieces are where jadeite earns its reputation: Jeannette canisters with their original lids sell for about $150-250, a Jeannette reamer for about $40-60, and scarce Fire-King Restaurant Ware forms such as the ball jug have been offered for several hundred dollars. McKee jadeite kitchenware, including canisters and shakers, sits in a similar range to Jeannette by form.
The color is the hook, but the maker and the form decide the price. A mug is a mug. A complete set of matching canisters, a butter dish with a correct lid or an uncommon Restaurant Ware piece is what collectors pay up for, and reproductions have followed the money since the 1990s.
Quick answer
- Fire-King cups, saucers, mugs, plates and small bowls: about $10-35 each.
- Jeannette jadite canisters with lids: about $150-250; reamers about $40-60.
- McKee jadeite canisters, shakers and bowls: roughly $25-200 depending on form.
- Scarce Fire-King Restaurant Ware and unusual forms: a few hundred dollars, with thin sales.
- Reproductions exist for many popular forms. Check the mark, the color and the mold detail.
How to identify and value jadeite, step by step
- Confirm it is glass, not stone. Jadeite glass is an opaque, milky green glass made mainly from the 1930s to the 1970s. It has nothing to do with jadeite gemstone, which is a separate market. If you have a jade bangle or carving, that is a gemstone question, not a glass one.
- Look for a mark on the base. Fire-King pieces from Anchor Hocking often carry an embossed or molded "Fire-King" mark, sometimes with "Oven Ware" or "Oven Glass" and "Made in USA". Many early Fire-King pieces and most Jeannette and McKee pieces are unmarked, except for some McKee pieces with an embossed "McK" in a circle.
- Name the line and pattern. Fire-King lines include Jane Ray (ribbed edges), Restaurant Ware (heavy, plain shapes made for diners), Charm (square), Alice, Swirl and Shell. Jeannette made "Jadite" kitchenware such as canisters, shakers and reamers. McKee made jadeite kitchen glass including canisters, bowls and refrigerator dishes.
- Judge the color. Original Fire-King jadeite varies from pale mint to deeper green within the same line. Jeannette tends to a slightly different tone. Reproductions are often too even, too dark or too bright.
- Check the mold detail. Original pieces show crisp edges, even ribs and smooth mold seams. Reproductions often have softer detail, thicker walls and rough or heavy seams.
- Check condition. Look for chips on rims and handles, wear on the bottom and scratching inside bowls. Crazing does not occur in glass, but heavy utensil marks and dishwasher dullness do.
- Check lids and labels. Canisters and butter dishes need their original lids. Canister labels in black lettering, such as SUGAR or COFFEE, should be crisp and intact.
- Price from sold results for the same maker and form. Asking prices for jadeite run far above what sells.
What jadeite sells for

| Piece | Maker | Recent sold range |
|---|---|---|
| Jane Ray cup and saucer | Fire-King | About $15-30 |
| Jane Ray dinner plate | Fire-King | About $10-25 |
| Restaurant Ware mugs, cups and plates | Fire-King | About $10-30 each |
| Restaurant Ware divided plates and berry bowls | Fire-King | About $10-40 each; sets of 10 to 15 bowls around $100-150 |
| Charm and Alice pieces | Fire-King | About $10-40 |
| Mixing bowls, Swirl or Beaded Edge | Fire-King | About $20-60 |
| Ball jug and other scarce Restaurant Ware | Fire-King | Several hundred dollars, sales are thin |
| Canister with lid, labeled | Jeannette | About $150-250 |
| Reamer | Jeannette | About $40-60 |

A mixed lot of common Fire-King and Jeannette jadeite tends to sell for about $50-150 in total, depending on how many pieces and how many have lids. Most single pieces sit at the low end of the table, and that is the honest price of a common jadeite cup.
The three makers in brief
Anchor Hocking's Fire-King is the jadeite most people own. It was oven-safe glass sold in stores and used widely as premiums, and Restaurant Ware was built heavy for diners and lunch counters, so large amounts survive. Jeannette Glass of Pennsylvania made its Jadite kitchenware earlier, mostly in the 1930s, and its canisters, shakers and reamers are scarcer and lighter in tone. McKee, also in Pennsylvania, made jadeite kitchen glass in the 1930s and 1940s, including canisters, measuring cups and refrigerator dishes, and its pieces are less often marked. Because Jeannette and McKee were made earlier and in smaller numbers, their best forms often outsell Fire-King, even without a mark.
Condition and what changes the price
| Factor | Effect on price |
|---|---|
| No chips, glossy surface | Full value for the form |
| Chip on rim or handle | Deduct about 40-60 percent |
| Dull surface from the dishwasher | Deduct about 20-40 percent |
| Canister missing its lid | Deduct about 50-70 percent |
| Canister label worn | Deduct about 20-40 percent |
| Clear Fire-King or McKee mark | Helps the sale and supports age |
| Original paper label | Small premium |
| Matching set of canisters | Adds over single pieces |
Spotting reproductions
Jadeite became a decorating trend in the 1990s and 2000s, and new green glass followed. Department store lines and small glassmakers produced jadeite-style dishes, and imports appeared with copied marks. A few checks help:
- Compare the mark. A Fire-King mark that looks too sharp, uses the wrong font or appears on a form Fire-King never made is a warning sign.
- Look at the color. Reproductions often have a uniform, slightly darker or yellower green than the period glass.
- Feel the weight and walls. Many reproductions are heavier with thicker walls.
- Check the detail. Soft ribs, blurry lettering on canisters and rough seams suggest a later mold.
- Look for wear. Period pieces usually have light wear rings on the base. A perfectly unworn base on a piece said to be 70 years old deserves a second look.
- Do not rely on UV. Some vintage jadeite glows under a black light and some does not. The glow is not a reliable test of age.
Common mistakes
- Treating all green milk glass as jadeite. Some green glass from other makers is a different color family and a different market.
- Pricing from asking prices. Jadeite listings often ask three or four times the sold price.
- Separating canisters from their lids. The lid is half the value of a canister.
- Overlooking McKee and Jeannette. Unmarked pieces from these makers can be worth more than a marked Fire-King mug.
- Ignoring reproductions. Popular forms such as butter dishes, canisters and salt and pepper shakers are the most copied.
- Selling a canister set split up. Matching sets with the same lettering style sell for more together than as singles.
- Using it in a hot dishwasher. The surface dulls quickly and the shine is part of the price.
How WorthPic reads jadeite photos
WorthPic runs on the newest and most capable AI model available, tuned for exactly this kind of identification. From a photo it reads the form, the line or pattern, the shade of green, any mark on the base, the lettering on canisters and visible condition. Those clues usually place a piece as Fire-King, Jeannette or McKee, and flag shapes or marks that do not fit the period. It then gives an honest value range for that maker and form.
What it cannot know is the weight in the hand, a hidden chip or every detail of a well-made reproduction. When the evidence is mixed, it says so. It identifies and estimates. It does not authenticate, grade or appraise.
What to photograph
- The piece from the side in daylight against a white background, so the color shows true.
- The base straight on, with any mark readable.
- Rims and handles close up for chips.
- Canister lettering close up, and the lid both on and off.
- A group photo if you are selling a set.
- A ruler next to unusual pieces, since size helps identify the form.
- The piece held toward a window, which shows the depth and evenness of the green better than a flash.
When to get it looked at in person
Common Fire-King cups, saucers and plates do not need an expert. Scarce Restaurant Ware, complete canister sets, McKee pieces you cannot find in references and anything that might be a reproduction are worth showing to a Depression glass dealer or a Fire-King collector club. They see reproductions every week. For related kitchen glass, see our guides to milk glass, Depression glass and vintage Pyrex, and to CorningWare for the white casseroles often stored alongside.
