Since the early 16th century coffin has been used to describe a container that holds dead bodies for burial. On the other hand, casket was originally used to describe a box used to store jewellery and other small valuable items before mid-19th century.
A coffin is constructed with six sides while a casket is typically a four-sided rectangular box and, often containing a split-lid for viewing purposes when used for burying people.
