A wooden coffin's average cost can range from $1,000 to $3,000. The average cost of a metal coffin, however, can rage from $900 to $7,000. It is also possible, and more cost-efficient, to rent a coffin for a viewing, and have the body buried in a casket shell. Another very cost-efficient way to purchase a coffin is online. Also, when browsing for coffins in a funeral home, ask if there are more in the back, seeing as they tend to keep the more costly coffins in the front, and the cheaper coffins in the back.
