This is a collection of over 10 pounds of bulk Lincoln Memorial circulated copper coins, minted in the United States between 1959 and 1981. The coins are made of 95% copper and have a total metal content of 10 LBS. These coins are perfect for collectors or those interested in investing in bullion.The coins are uncertified and have not been modified. They come in a unit quantity of 10 plus pounds and are sold in a lb unit type. The coins are shaped like coins and have a fineness of 0.950. The brand/mint is U.S. Mint. This collection is a great addition to any collection or investment portfolio As copper ore quality continues to decline, copper bullion prices will continue to rise. This is a good investment. I hand sorted these coins and extra pennies are included to compensate for sorting errors. I have prior to shipping went through the pennies a second time and culled out any mistakes or coins that are in very poor shape.
