Early poker chips were made from a variety of materials, including ivory, bone, wood, paper, and clay
In the early days of poker, players used whatever small valuable objects they had at hand, including gold nuggets, stones, gems, and wood. As the game became more established, players began using standardised betting tokens made from a variety of materials, including ivory, bone, wood, paper, and clay. These early poker chips, used in the 19th century in places like Louisiana, were made from a mixture of these materials, with clay holding them together. Riverboat gamblers in the 1800s prized their personal sets of poker chips, carrying them from place to place and game to game.
Ivory poker chips, made from the middle of the 19th century, can be found in as many as two thousand different designs and styles. Ivory chips are often hand-engraved, carved, or otherwise designed, making each one unique. This was an effort to stop chip counterfeiting, which was a growing problem in the 1880s when composition chips were introduced. These new chips were made from clay and shellac and often copied earlier ivory chip designs.
As the game progressed, clay became the primary material for poker chips, with companies developing ways to compress clay into moulds at high pressures and temperatures, creating more durable tokens. However, pure clay chips were not very durable, and they were prone to cracking and fading. So, starting in the 1950s, manufacturers began mixing clay with sand and other materials to create stronger chips with distinct colours and markings.
By the 1940s, the plastic industry was expanding rapidly, and plastic poker chips started to become more common. Injection-moulded plastic chips were first made in 1965, and plastic chips are now the most common type used outside of casinos. Today, casino chips are typically made from a clay composite or ceramic material, with plastic chips also being used in some casinos.

In the 19th century, clay became the standard material for poker chips
In the early days of poker, players used a variety of objects as tokens for betting and keeping score, including small stones, beads, and pieces of metal. As the game grew in popularity, particularly in the 19th century, there was a need for a more standardized and consistent form of currency specifically designed for poker. This led to the invention and widespread use of poker chips.
During the 19th century, clay became the standard material for manufacturing poker chips. This shift occurred because clay is a durable and malleable material that can be easily molded into uniform discs. Clay chips also have a distinctive feel and sound when stacked and shuffled, enhancing the tactile experience of playing poker.
The composition of clay poker chips has evolved over time. Modern clay chips are not actually made of pure clay; they are a mixture of clay, compressed clay, and other materials such as sand, chalk, and acrylic. This composite material combines the benefits of clay's texture and durability with the added strength and consistency provided by other substances.
Clay poker chips typically have a metal insert embedded in their center. This insert, usually made of brass, adds weight to the chip, giving it a satisfying heft and improving its handling qualities. The metal insert also ensures that the chip can withstand frequent use without cracking or breaking, making it suitable for casinos and high-stakes games.
The design and production of clay poker chips became an art form, with manufacturers creating intricate and beautiful designs. Customized poker chips with unique colors, patterns, and imprints became popular, allowing players to express their personal style and casinos to promote their brand. The use of clay also enabled the implementation of security measures, such as watermarks and RFID technology, to prevent counterfeiting and protect the integrity of the game.
By the end of the 19th century, clay poker chips had firmly established themselves as the standard gaming token in casinos and card rooms worldwide. Their durability, uniformity, and tactile appeal contributed to the growing popularity of poker and helped shape the modern gaming industry. Today, clay chips remain a beloved aspect of poker culture, valued by players for their nostalgic feel and association with the rich history of the game.

Post-WWII, other materials were mixed with clay to increase durability
The history of poker chips is a long and varied one, with materials ranging from ivory, bone, and wood to clay and plastic. While clay chips were popular in the 1800s, they began to be replaced by other materials after World War II. This was due to a demand for more durable chips that were less brittle and easier to handle.
During the post-war period, poker chips began to be made from a composite of materials, including clay, plastic, and metal. These composites were designed to mimic the touch and feel of traditional clay chips while offering increased durability. The exact composition of these chips varied, with some made from a mixture of fine clay minerals and resins, while others included earthen materials such as sand, chalk, and clay similar to that found in cat litter.
The use of plastic in poker chips also became more common during this time. Injection-molded plastic chips were first introduced in 1965, offering a cheaper alternative to clay composite chips. The development of injection molding technology played a significant role in the production of plastic chips, with the first injection molding press invented in 1919 and the first injection molding of plasticised cellulose acetate patented in 1939.
While clay composite chips continue to be used in casinos, they are now often made with a metal core to increase their durability. Ceramic chips, introduced in the mid-1980s, have also gained popularity due to their ability to be printed on the entire surface, allowing for more intricate graphics and designs.
Today, poker chips can be found in a variety of materials, including plastic, clay composite, ceramic, and even metal, each offering its own advantages in terms of cost, durability, and customisation.

Injection-molded plastic chips were invented in 1965
The history of poker chips is a long and varied one, with materials ranging from clay to ivory, bone, wood, paper, and even gold. The first poker chips used in Louisiana in the 19th century were made from a mixture of these materials, held together by clay. Over time, the composition of poker chips evolved, with clay becoming the primary material in the 19th century, and later, a mixture of clay and shellac.
By the early 20th century, with the invention of the first injection moulding press by Arthur Eichengrün in 1919, the plastic chip began to emerge. Japan was an early producer of plastic chips, using celluloid, shellac/resin, and colouring material. However, it wasn't until 1965 that the first injection-molded plastic chips were invented. This innovation marked a significant shift in the production of poker chips, making them more affordable and widely accessible.
The post-World War II era saw a surge in the use of plastic in poker chip manufacturing, as producers sought to create more durable and inexpensive chips. By the 1950s, plastic moulders were cropping up everywhere, and injection-molded or hard plastic chips could be produced at a fraction of the cost of their clay predecessors. This shift towards plastic chips also aligned with the growing popularity of poker and card games during this time.
Today, most poker chips are made of plastic with ridges for easy stacking. However, some casinos still use clay chips, now composed of a clay-composite material, often over a metal core. These chips are heavier and produce a deeper sound, contributing to a more tactile and sensory gaming experience.
The evolution of poker chips didn't stop with plastic, though. In the mid-1980s, ceramic chips were introduced, offering a new level of customisation with the ability to print lettering and graphics on the entire surface. These ceramic chips, sometimes referred to as clay composite, are made with a special plastic or resin formula, providing a similar feel and sound to ceramic or porcelain.

Over time, the need for standardization led to the creation of specialized tokens made from materials like ivory and clay.
Today, poker chips are mostly made from plastic with ridges that allow them to be stacked easily. However, there has been a shift towards composite materials that mimic the feel of traditional clay chips. These modern chips are made from a mixture of materials, including sand, chalk, and clay, to create a more durable product that is less brittle than its predecessors. This shift began after the Second World War, when clay chips began to be mixed with other materials to improve their durability.
The use of composite materials offers several advantages. Composite chips are long-lasting, less expensive, and easier to handle than traditional clay chips. They stack and riffle easily, slide smoothly across tables, and produce a satisfying sound when splashing a pot. Additionally, their heavier weight compared to plastic chips makes chip tricks easier to perform.
While clay chips are still favored by traditionalists, composite chips have become the go-to choice for most players. The introduction of composite materials has democratized the poker chip market, making high-quality chips more accessible and affordable for players worldwide. This evolution in materials has played a significant role in the growing popularity of poker and casino games, both in physical casinos and online.
