A "sikke" is a type of coin that has historical significance in various cultures, particularly in the Middle East and South Asia. The term is often associated with the currency used in the Ottoman Empire and later in India, where it represented a standard unit of trade. Sikks were typically made of precious metals like silver or gold and were used for everyday transactions. In modern times, the term "sikke" may also refer to commemorative coins or tokens that celebrate cultural heritage. Collectors often seek these coins for their historical value and artistic design. The study of sikke can provide insights into the economic and social conditions of the periods in which they were used.
