can you flip a coin on its side
Coin flipping It is possible for a coin to land on its edge, usually by landing up against an object (such as a shoe) or by getting stuck in the ground. However, even on a flat surface it is possible for a coin to land on its edge, with a chance of about 1 in 6000 for an American nickel.[3] Angular momentum typically prevents most coins from landing on their edges unsupported if flipped. Such cases in which a coin does land on its edge are exceptionally rare and in most cases the coin is simply re-flipped.[4]
Half crown (British coin) The half crown was a denomination of British money, equivalent to two shillings and sixpence, or one-eighth of a pound. The half crown was first issued in 1549, in the reign of Edward VI. No half crowns were issued in the reign of Mary, but from the reign of Elizabeth I half crowns were issued in every reign except Edward VIII, until the coins were discontinued in 1967.
