Trade among early Filipinos and with neighboring islands was conducted through barter. Gold and piloncitos (small bead-like gold bits) later emerged as early mediums of exchange. For at least 2,000 years before the Spanish arrival, small seafaring Filipino communities traded with Malaysia, Vietnam and China through barter. During the Spanish period, various coins circulated, including Toston coins brought by Magellan in 1521 and banknotes issued by El Banco Espanol Filipino de Isabel II, the country's first commercial bank. Philippine numismatics continued developing through U.S. occupation, the Japanese invasion, independence and the establishment of the Central Bank of the Philippines in 1949
