In 2013, two rare Mughal gold coins from the 17th century, minted during the reigns of emperors Jahangir and Shah Jahan, went up for auction in Geneva, Switzerland. The Indian government tried its best to stop this private sale, since it considered the coins to be “national treasure”. But it failed. The auction eventually didn’t take place either, though, after buyers developed cold feet due to a crashing stock market. Nonetheless, both coins went missing thereafter, and they haven’t been traced ever since. No one seems to know where they are right now.
