In September 2008, the rare 1/4 ounce Ecuadorian gold coin sold for a record price of $2,800 on Ebay Live Auctions. Estimates during the time of the sale were only between $ 1,000 and 1,200, with previous sales averaging $ 1,250.
Depicting the "Gentleman King," the 5 Franc silver coin is a great complement to any collection. In spite of the recent correction in the silver prices, the Louis-Philippe has maintained its enormous price-to-silver ratio. Considering that the market price of silver is presently at about $14 an ounce, it's easy to see why this .90 oz. silver coin is such a good investment.
Also known as the Liberty Head, this one ounce coin has recently become one of America's most popular historic coins. The rarest types are the 1879-O and 1886, which sell for over $20,000.

Although hundreds of millions were minted and circulated, they're an essential part of nearly every American numismatic collection.

Although these coins haven't been around for 5 years, they've quickly become a favorite amongst collectors. Months after the US mint issued them in June 2006, they became available on Ebay for as little as $600. Now, the average cost is $1,250, well above the present market price of gold. Since its debut, the Buffalo head has appreciated at an annual rate of 80%.
Minted only in 1930, this 1/4 ounce gold coin fetches about $360, about 50% higher than the market price of gold. According to the Standard Catalogue of World Gold Coins, "Only 14,415 were released. Remainder withheld."
Five years ago, the Austrian coin was so undervalued that it was selling for as much as or often less the market price of gold. Today, the coin sells for an average of $1,100, more than 20% higher than gold's current market price.
