About this 3D model

"The copper piece is generally considered to be a coin, though ingots or trade bars made of copper or other materials may be worth multiple copper pieces or even fractions thereof. In coin form, it is generally described as “approximately the size and weight of a United States half-dollar coin” meaning 30.6mm in diameter and weighing 11.5 grams (approximately 40 to a pound)." - dungeonsfandom.com
