The earliest known marbles were made of stone, marble or clay. Coloured glass marbles were used in 15th-century Germany. China and pottery marbles were used in the 1800s. Varieties of blown glass marbles were available from 1870 to 1890 in many colours and patterns. Agate, marble and stone marbles continued to be popular until the first machine for creating marbles was invented in 1890. Older marbles in good condition are hard to find, as most were used to play marble games, and can be very expensive.
Extremely rare marbles
Sulphides are the most sought-after marbles. These are made of clear glass with a clay figure in the centre. The figures may depict animals, famous people, flowers, trains or many other subjects. Sulphide marbles can bring you several thousand pounds (dollars) in the marketplace. Coloured sulphide marbles are very rare. End of the Day marbles were made with leftover glass at the end of the manufacturing day. These marbles will have a pontil mark left by the glass blower's rod on one side and are extremely scarce. Ruby Red Mica Snowflake marbles also sell for thousands of pounds (dollars). These transparent glass marbles come in all colours and contain mica chips.
Very rare marbles

Highly prized marbles
Hand-painted china marbles made from 1860 to 1890 were produced in Germany. These are valued from £97 to £162 each. Handcrafted and designed marbles are slightly more valuable, selling for £178 to £227. Carnelian, cobalt, malachite, jade, jasper, onyx, quartz and tiger eye, among others, can still be found. The price range can be £32 to £325, depending on how badly a buyer wants to add a marble to a collection.
Lower value marbles
Solid Core Swirl marbles, made in 1998, surprisingly have a value of £16 to £26 each. Older clay, handmade marbles are simple and lack decoration; prices for these may be less than £32. Steelies are metal marbles normally made for industrial use, and are fairly common. Almost every marble collection contains a few inexpensive Steelies.
