The 2012 1 oz Copper Walking Liberty rectangle is a commemorative bullion piece minted with .999 pure copper. These items are often referred to as "bars" or "ingots" due to their rectangular shape, distinguishing them from the more common round versions.
- Design: The obverse features the iconic "Walking Liberty" image originally designed by Adolph A. Weinman, while the reverse typically depicts an American Eagle or heraldic shield accompanied by the weight and purity.
- Specifications: Struck in 1 avoirdupois ounce of .999 fine copper. While rounds are typically 39mm in diameter, the dimensions of the rectangular version vary by mint.
- Collectibility: While they carry the "2012" date, they are not legal tender and are valued primarily for their copper content and artistic design
