Historical and patriotic, the Lincoln Steel Penny Dog Tag Coin Necklace is spirited with a unisex flair. A silver tone 1.88 inch by 1.13 inch dog tag holds a Steel Penny minted for only one year in 1943 due to a copper shortage during WWII. The coin dog tag is accompanied by an American flag charm. Together they hang from a 22 inch silver tone ball chain with a 3 inch extender and a lobster claw clasp. The Lincoln Steel Penny is coated in zinc and is the only magnetic US coin of regular issue. The unisex necklace comes in a white jewelry box and includes a Certificate of Authenticity. All mint marks and years will vary.
