 Sceptics suggest that the bracelets could have been produced in modern times from metal obtained by melting ancient gold coins, Dacian coins of the KOSON type or Greek Lysimachus coins; however, the analyses performed so far do not confirm the use of gold from these coins in the bracelets' manufacture.It is most likely that no other group of ancient goldwork has been more thoroughly examined by scientists, technologists and scholars in various countries and various institutions than the Dacian gold spirals with dragon terminals found between 1999–2001 at Sarmizegethusa.In each case-study, and completely independent from each other, their examinations led to the same conclusion.
