For every Olympic games, a unique design for the medals is created. It is supposed to show the culture and the symbols of the host country. So, the weight of the medals may vary. Besides, since the 1912 Stockholm Olympics, the medals are not made from pure metals, but are only covered with them. For example, in Pyeongchang, the gold medal was covered with approximately 6 grams of gold. So, it is pointless to melt these prizes and sell the metal. However, these trophies can cost from $20 to $50 thousand in auctions.
