Interesting article. I can't believe a winter medal is worth more than a summer, although for me it would all depend on the sport:

Everybody who calls me and says, 'I want to sell a medal' and I give them a quote of what medals usually bring — they are totally disappointed," said O'Neil, who has auctioned Olympic memorabilia for 25 years. "They can't believe it. They think, 'OK, Jesse Owens' medal went for $1.4 million, mine should be worth at least $200,000 or $300,000.'"
Instead, O'Neil estimates that the most common bronze medal from the Summer Olympics should bring $5,000-$6,000, a silver $8,000 and a gold $10,000. In addition, gold medals have not been solid gold since 1912. They are mostly silver.
Winter Olympic medals are rarer because there are fewer athletes and events. They can range from about $10,000 to more than $30,000.
