Challenge coins represent unity, morality, respect towards one another, appreciation for outstanding commitment in duty and camaraderie within the department. All the branches of armed forces use challenge coins representing their departmental emblem. It isn’t unusual for soldiers to receive challenge coins, especially if they have been posted on different missions in different units. Each challenge coin awarded speaks about the bravery, sacrifices and courageous heart of soldiers. To respect their bravery, these challenge coins are awarded in all the departments - Navy, Army, marine, coastal guard, police, fire fighter and many more. Few wear challenge coins on their shoulders; few keep them in their wallets or hang them around the neck as is customary. The history of the challenge coin dates back to the First World War. The same traditional practise is still being followed and nowadays you can see many customized challenge coins in corporate, business, agencies, branded shops, schools and institution, even in celebration and wedding.
