Coin flipping
Coin flipping, coin tossing, or heads or tails is the practice of throwing a coin in the air and checking which side is showing when it lands, in order to choose between two alternatives, heads or tails, sometimes used to resolve a dispute between two parties. It is a form of sortition which inherently has two possible outcomes. The party who calls the side that is facing up when the coin lands wins. Coin flipping was known to the Romans as navia aut caput ("ship or head"), as some coins had a ship on one side and the head of the emperor on the other.
Coin collecting
Coin collecting is the collecting of coins or other forms of minted legal tender. Coins of interest to collectors often include those that were in circulation for only a brief time, coins with mint errors, and especially beautiful or historically significant pieces. Coin collecting can be differentiated from numismatics, in that the latter is the systematic study of currency as a whole, though the two disciplines are closely interlinked. Many factors determine a coin's value including grade, rarity, and popularity.
