They are found naturally and were the first three elements known to man. They were all used as primitive money well before the first gold coins which appeared in Egypt around 3400 BC. There are 35 isotopes of gold, with mass numbers ranging from 171 to 205. These are the artificially produced isotopes of gold. The natural gold consists of one stable isotope, Au-197, which is the only stable isotope. The isotopes with atomic masses above 197 decay by emission of β rays.
