Igbo Bochie or Twisted Manilla Currency

Twisted like rope, and about as hard to forget.

Igbo people of central Nigeria, West Africa, used the bochie, or twisted manilla, as currency in the 20th century. Manillas of copper and its alloys were traded in large numbers and are also associated with bridewealth and prestige. This one is a closed loop of tightly wound strands, the ends overlapping in a small knot at the top. The twist is crisp and regular. A mottled green patina lies over rusty-orange metal.

About 8 inches across. Hang it on a nail and call it a wreath for a banker.
