Antique cameo jewelry pieces often cost between $25 and $100 on eBay as of 2015. Rare cameos and those made from higher quality materials may have a value of $200 or more. A cameo's maker and its age also affect its value.
Cameos produced after World War II tend to feature inexpensive plastic and glass materials, and they are accordingly less valuable than older cameos. Cameos from before the war more often feature ivory and are set in precious metals, which contribute to their higher values. Additionally, the subject matter of a cameo may help determine its age and value. Early cameos often feature real historical figures, while later cameos often depict anonymous women or mythological figures.
