Glass coins are very rare.
Early Islamic coin weights were made of glass.
"Account marks" issued by the Duke Spremont in Maehren were also made of glass.

Porcelain coins were very popular because of their beauty but unpractical because they broke very easily. After a state law against the making of emergency money in 1922, porcelain coins weren't used as monetary units, but we still see porcelain medallions now and again.

Coins made of porcelain belong to the category of "emergency money". The State Porcelain Manufacturer Meissen produced porcelain coins made of white fine china or of brown stoneware with golden or coloured decorations.

White porcelain coins with coloured characters were used in casinos in Siam (today's Thailand) as marks or private coins.
