As far as the value of the raw materials in them, this varies from Olympiad to Olympiad.  For the recent 2012 Olympics in London, the medals were the largest of any in Summer Olympic history up to that point, weighing in at 400g for the gold medal.  Of this 400g, 394g was sterling silver (364.45g silver / 29.55g copper) with 6g of 24 karat gold plating.  At the price of gold and silver when these medals were won by various Olympians, this means a gold medal in the London Olympics was worth about $624, with $304 of the value coming from the gold plating and about $320 coming from the sterling silver. Since then, the price of gold has dropped about 18% and the price of silver has dropped about 39%.

For the current 2016 Rio Olympics, the gold medals are one-upping the London Games, weighing in at a a half a kilogram, with about 462g of it silver, 6g gold, and the rest copper.  So by current gold and silver prices as of July 13, 2016, these medals are worth about $561 total, with approximately $301 of the value from silver and $260 from gold. So, despite being 1/5 more massive than the London Games Olympics medals, and having the same amount of gold and much more silver, due to the significant drop in gold and silver prices since 2012, the Rio gold medals are worth less at their awarding than the London Games medals were worth when they were awarded.

Of course, athletes can often get much more than this selling the medals on the open market, particularly for momentous medals, like the “Miracle on Ice” 1980 men’s U.S. hockey team gold medal.  Mark Wells, a member of that team, auctioned his medal off in 2012 and received $310,700 for it, which he needed to help pay for medical treatment.
Most auctioned medals don’t go for nearly this much, though.  For instance, Anthony Ervin’s 50 meter freestyle gold medal won in 2000, even with all proceeds going to the victims of the Indian Ocean tsunami, only sold for $17,100.  John Konrads’ 1500 meter freestyle gold medal won in 1960 only sold for $11,250 in 2011.  This is a great return in terms of what the raw value of the materials are worth, but certainly nowhere close to Mark Wells’ medal.

Gold medals in the Olympics weren’t always made mostly of silver.  Before the 1912 Olympics, they were made of solid gold.  However, they tended to be much smaller than modern medals.  For instance, the 1900 Paris gold medals were only 3.2 mm thick, with a 59 mm diameter, weighing just 53g.  For perspective, the London 2012 medals were 7 mm thick, with a diameter of 85 mm and, as mentioned, weighed 400g.  The 1900 Paris gold medals at today’s value of gold are worth about $2300.  For the 1912 games in Stockholm, the last year the gold medals were made of solid gold, the value of the gold medals at current prices of gold would be around $870.

If the current 2016 Olympic gold medals were made out of solid gold, they’d be worth about $21,625 each.  This may seem feasible, considering how much money the Olympics brings in, until you consider just how many medals are awarded during each summer Olympics.  For instance, in these 2016 Olympics, about 2,488 medals have been produced, including 812 gold medals. At $21,625 each, that would be just shy of $18 million dollars for the gold medal materials alone.

As it is, with the current gold medals having about $561 worth of materials, then $305 for the silver medals, and about $5 for the bronze (which are mostly made of copper, with a very small amount of zinc and tin), about $708,000 is still being spent on the raw materials alone for these medals, not to mention the cost of having them minted.
