You are looking at a gorgeous solid 925 sterling silver necklace with an authentic US 1961 Roosevelt dime 90% silver BU Uncirculated Proof coin. The coin is set with backside 4-prong. The pendant is made of solid 925 sterling silver, sized about 29mm(1.16") x 23mm(0.92"). It comes with a 18" solid 925 sterling silver chain, and also a gift box. I hope you end up with one of these beautiful coin necklaces. This necklace will be great for gift, investment purpose or just adding to your coin/jewelry collection. Both chain and pendant are marked 925 sterling silver. The areas of the photo's that appear black are in fact mirror like and not the color black. What you see is merely a reflection of the camera lens in a macro photo setup. Just wanted to make sure this is clear for our buyers! Thanks!
