puncheon

The original and prime meaning of the word puncheon is a tool or instrument for piercing or punching, such as those used for impressing designs onto coin dies. The "barrel" meaning is thought to derive from the fact that it would have been marked by use of a punch to denote its contents.A puncheon is also a type of road, see plank roadThe puncheon, in the United States also called pon for brevity, is an old English unit of wine casks, holding about 318 litres. It is also known as tertian (from the Latin word for third), because three of it make a tun, and as the (wine) firkin.
