what is the shield on the back of a penny
Penny (United States coin) The United States one-cent coin, often called penny, is a unit of currency equaling one-hundredth of a United States dollar. The cent's symbol is ¢. Its obverse has featured the profile of President Abraham Lincoln since 1909, the centennial of his birth. From 1959 (the sesquicentennial of Lincoln's birth) to 2008, the reverse featured the Lincoln Memorial. Four different reverse designs in 2009 honored Lincoln's 200th birthday and a new, "permanent" reverse – the Union Shield – was introduced in 2010. The coin is 0.75 inches (19.05 mm) in diameter and 0.0598 inches (1.52 mm) in thickness. Its weight has varied, depending upon the composition of metals used in its production (see further below).
Penny board A Penny board is a type of plastic skateboard, known within the industry as a short cruiser. The term "Penny" is synonymous with "Penny Skateboards", an Australian-based company founded in 2010 by Ben Mackay.[1] Penny is a registered trademark for skateboards, but has been widely generalised to describe all small plastic skateboards due to the brand's popularity. Penny Skateboards revived the plastic skateboard category by pairing a high quality plastic deck with cruiser wheels and trucks. This combination now epitomises a "Penny board" in generic terms. Penny Skateboards was named after Ben Mackay's sister, Penny.
