This tuxedo stud set includes 4 studs and 1 pair of cufflinks and is sure to be a stand out accessory at any black tie event! Each portrait is pierced out from American currency - half dollars, quarters, nickels, dimes and pennies. Ben Franklin, JFK, George Washington and FDR are made from the actual silver half dollars, quarters and dimes. Thomas Jefferson and Abraham Lincoln from the nickel and penny were cut from the coin, molded and cast in silver so that the set would be entirely silver. The stud and cufflink backings are also solid sterling silver.
