Antique pottery is one of America’s most popular collecting categories, with millions of pieces changing hands each year at estate sales, antique shows, and online auctions. Whether you inherited a piece with an unfamiliar mark, spotted something promising at a flea market, or are building a focused collection, this guide covers everything you need to identify, date, and value American and European antique pottery.
What Is Antique Pottery?
Legally, an antique is an object at least 100 years old. In the pottery market, the most actively collected American studio and art pottery was produced between roughly 1880 and 1960 — making pieces from that era either true antiques or well-established vintage collectibles. “Vintage” pottery typically refers to pieces from 1920 to 1980 that command collector interest even if they haven’t reached the 100-year threshold.
American art pottery differs from everyday dinnerware in key ways: it was typically hand-decorated or hand-finished, made with distinctive glazes, and produced by named potteries whose marks carry value. The major American art pottery centers were Ohio (Roseville, Rookwood, Weller, Hull), Ohio/Missouri border (Red Wing, McCoy), and New England (Grueby, Hampshire).
Major American Antique Pottery Brands
McCoy Pottery (1848–1990)
McCoy is the most widely recognized American pottery brand and the most frequently found at estate sales. The Brush-McCoy and Nelson McCoy Sanitary Stoneware Company (later simply McCoy Pottery) produced cookie jars, planters, vases, and garden ware from the 1910s through the 1980s. Cookie jars — particularly the Mammy, Indian, and Dalmatian designs — are the most valuable McCoy pieces, often fetching $100–$500+. See our complete McCoy Pottery guide →
Roseville Pottery (1890–1954)
Roseville Pottery of Zanesville, Ohio is among the most prestigious American art pottery makers. Their mold-cast art lines — Pinecone, Wisteria, Futura, Blackberry, Morning Glory — feature naturalistic designs with distinctive matte and semi-matte glazes. Roseville pieces are marked with either the raised “Roseville” script in a circular cartouche, the Rv in-mold mark, or the older RRP Co. stamp (which confusingly stands for the earlier Robinson-Ransbottom Pottery Company, not Roseville). See our complete Roseville Pottery guide →
Weller Pottery (1872–1948)
Weller Pottery, also from Zanesville, Ohio, was the largest pottery manufacturer in the United States during the early 20th century. Their art lines — Sicardo (iridescent metallic glaze), Hudson (underglaze floral), Louwelsa (brown-glaze), Dickensware (incised figures), Coppertone (green-and-bronze frog motifs), and Woodcraft (realistic bark texture) — represent some of the most technically ambitious American art pottery ever produced. Sicardo pieces by Jacques Sicard can sell for $5,000–$50,000. See our complete Weller Pottery guide →
Rookwood Pottery (1880–present)
Rookwood Pottery of Cincinnati, Ohio is widely regarded as the finest American art pottery producer. Founded by Maria Longworth Nichols in 1880, Rookwood won the Grand Prix at the 1900 Paris Exposition and set the standard for American art pottery. Pieces are identified by the reverse-RP flame mark (one flame added each year through 1900, then Roman numerals for the year thereafter) plus a shape number and artist cypher. Decorator attribution is critical to value: pieces by Kataro Shirayamadani, Matthew Daly, or Albert Valentien routinely sell for $5,000–$50,000+. See our complete Rookwood Pottery guide →
Hull Pottery (1905–1986)
Hull Pottery of Crooksville, Ohio produced pastel matte-glaze art pottery from the 1930s through the 1950s. The pre-1950 lines — Little Red Riding Hood, Bow-Knot, Wildflower, Water Lily, Magnolia — are the most sought-after and are distinguished by their soft, blended pastel glazes and molded floral decorations. Hull pieces are marked “Hull” or “Hull Art U.S.A.” with a shape number. Little Red Riding Hood pieces (a licensed pattern) typically sell for $40–$400 depending on the form.
Red Wing Pottery (1877–1967)
Red Wing Union Stoneware of Red Wing, Minnesota produced utilitarian stoneware (crocks, jugs, churns) through the early 20th century, then transitioned to art pottery and dinnerware. The original salt-glazed stoneware crocks with the red wing logo are the most actively collected Red Wing pieces, particularly the “elephant ear” and “wing with 4” early designs. Dinnerware patterns (Bob White, Tampico, Lexington) attract a separate collector base.
European Antique Pottery
Majolica
Majolica is a tin-glazed earthenware with opaque white glaze and colorful enamel decoration. True Italian maiolica (the original spelling) dates from the 15th century; English majolica from the Victorian era (1850s–1900) — made by Minton, Wedgwood, and George Jones — is the most actively traded antique majolica in American markets. Victorian majolica is identified by its high-relief molded designs, vivid yellow/turquoise/cobalt glazes, and molded or impressed marks on the base.
Delft
Delft is a blue-and-white tin-glazed earthenware named for Delft, Netherlands. Genuine antique Dutch Delft (pre-1800) is rare and valuable; the most common “Delft” found at antique markets is Delftware made in the 20th century by Royal Delft (De Porceleyne Fles) or German/English imitations. Authentic pieces have hand-painted cobalt designs, a tin-glaze white ground, and a mark that can be identified by the specific pottery’s logo and date code.
Staffordshire Figures
English Staffordshire pottery figures — dogs, horses, cottages, and portrait busts — were mass-produced in the Staffordshire Potteries from the 1840s through the early 1900s. The iconic King Charles Spaniels (Wally dogs) are the most recognizable form. Antique Staffordshire is unglazed on the back (“flat-backed” for mantelpiece display), has hand-painted enamel decoration, and often has slight asymmetry from hand-pressing. Reproductions have perfect symmetry and machine-smooth paint.

How to Authenticate Antique Pottery
Check the Glaze
Authentic pre-1960 art pottery glazes were applied by hand, fired at high temperature, and show natural variations: slight color shifts, drips, pooling in crevices, and a depth that mass-production glazes lack. A completely uniform, “plastic” glaze on a piece claimed to be early American art pottery is a warning sign. Crazing (fine crackle in the glaze) is common on genuine antique pottery and is not a defect — it’s caused by the glaze and clay body contracting at different rates over decades.
Examine the Mark
Marks on genuine antique American art pottery are typically impressed into the clay before firing (Rookwood, Roseville) or hand-stamped in ink (McCoy). Raised marks (part of the mold) are used for mass-produced lines. A mark that looks printed on top of the glaze, or is suspiciously crisp and uniform, may indicate a later reproduction. Cross-reference any mark with a pottery reference guide or the major databases (American Art Pottery Association, Kovels).
Look for Hand-Finishing Signs
Most genuine American art pottery shows evidence of hand-finishing: slight texture variations in the clay, small tool marks in recessed areas, or minor asymmetry in thrown or hand-shaped pieces. Slip-cast pieces (poured into molds) are more uniform, but even these typically show hand-applied glaze and decoration on art pottery lines.
Know the Specific Reproduction Problem Areas
Roseville: Reproductions of Pinecone, Blackberry, and Wisteria pieces exist. Genuine Roseville has deep, saturated glaze colors; reproductions often appear washed-out. The Rv mark on reproductions is often too crisp or applied over glaze.
Rookwood: Very few reproductions exist because the flame mark system is complex to fake. Beware of decorator cyphers added to genuine but undecorated commercial pieces.
McCoy: Fake McCoy marks exist on non-McCoy pieces. The genuine McCoy impressed mark is in the clay; fake marks are often applied over glaze as decals or added ink stamps.

Frequently Asked Questions
What is the most valuable American pottery brand?
Rookwood Pottery consistently produces the highest prices at auction. Major decorated pieces by top decorators (Kataro Shirayamadani, Matthew Daly, Albert Valentien) regularly sell for $10,000–$100,000+. Weller Sicardo by Jacques Sicard is the second-most valuable American pottery line. Roseville Blackberry and Wisteria are the most actively traded high-value Roseville lines.
How do I know if my pottery is valuable?
Four factors determine pottery value: maker (Rookwood > Roseville > Weller > McCoy in general prestige), decorator (named artist attribution dramatically increases Rookwood and Weller values), condition (chips, cracks, and repairs reduce value by 50–90%), and rarity (unusual forms, rare colorways, and documented exhibition pieces command premiums). Check completed eBay sales for your specific piece’s mark and form as a starting market reference.
Is McCoy pottery marked?
Most McCoy pottery is marked, but not all. Early Brush-McCoy pieces (pre-1920s) are often unmarked. The Nelson McCoy Sanitary Stoneware Company used “McCoy” impressed into the clay from the 1930s onward. The “NM” mark appears on some mid-century pieces. Many cookie jars are marked “McCoy USA.” Unmarked pieces can still be attributed by shape and glaze if they match documented McCoy forms.
What does RRP Co. mean on pottery?
RRP Co. stands for Robinson-Ransbottom Pottery Company of Roseville, Ohio — not Roseville Pottery. This is one of the most common confusions in American pottery collecting. RRP Co. pieces are not Roseville Pottery and have much lower collector value. Genuine Roseville Pottery pieces are marked “Roseville” in script, “Rv” with a shape number, or with the Roseville paper label on very early pieces.
How can I identify Roseville pottery?
Look for the raised Roseville script mark in a circular cartouche on the base (post-1940s production), the “Rv” mark with a shape number (1930s–1940s), or “Roseville Pottery” impressed marks on early pieces. The most collectible lines — Pinecone, Blackberry, Wisteria, Futura, Morning Glory — have distinctive molded naturalistic designs and rich glaze colors. The RRP Co. mark (a common fake-out) belongs to a different, less valuable pottery.
Is antique pottery safe to use?
Decorative antique pottery (vases, figurines, planters) is generally safe to display and handle. However, using antique pottery for food or beverages is not recommended: lead-based glazes were commonly used before the 1970s, and acidic foods (coffee, juice, vinegar-based sauces) can leach lead from the glaze. If you want to use antique pottery for serving, test it with an at-home lead test kit first, and do not use any piece with crazed, chipped, or peeling glaze for food service.
