The medals themselves are of little comparative physical value.
Gold medals at the London Games are made largely of silver with a thin gold coat and some copper which values them at $706 by current prices, according to the World Gold Council.
In fact, for the first time, the silver content in the 2012 medals is worth more than the gold.
But a gold medal can give athletes the Midas touch with sponsors, or, for some medallists, offer an attractive resale value.
The marketing value of a gold medal varies from sport to sport and country to country but could translate into sponsorships worth millions of dollars.
Swimming, track and field, and gymnastics attract the most interest from sponsors.
Here is a list of the prizes on offer for gold medal winners of eight nations competing at the London Games.
The United States
The United States pays $NZD 31,000 to gold medallists.
Australia
Australians receive $NZD 26,000, are featured on an Australia stamp, and get a flight upgrade home.
Singapore
Singaporean athletes are being offered one of the biggest incentives with an offer of 1 million Singapore dollars ($NZD 989,000) for a gold. Singapore has never won gold at the Olympics.
Russia
Russia has promised athletes $NZD 166,000 for golds.
Italy
There are reports Italy has offered $NZD 224,000 for gold.
China
China, which is jostling with the United States for top of the gold medals tally, has not released details of financial incentives but the Chinese language Sports Weekly reported they were likely to hand gold winners $NZD 63,000.
India
India has promised coaching jobs to athletes who win medals.
Great Britain
British athletes, however, will have to settle for national glory and their image on a stamp rather than cash.
