This one isn't going to win any points for fashion design in my opinion but as an investment it might be pretty smart considering recent gold prices. Yesterday Japan's largest bullion house showed off a gleaming gown which is covered with hundreds of gold coins. Pity the poor model wearing it. Mayuka, the model weighs around 110 pounds and the dress is close to 18 pounds. The dress was made using 325 Austrian gold coins issued to commemorate the Vienna Philharmonic and is valued at $275,000. There are no plans to offer the dress for sale.

It's everybody's dream to suddenly find a rare coin floating around in their pocket or purse and be an instant millionaire, and although that's always possible (not all the rare coins in the world are accounted for) it's pretty unlikely. Coin collecting is big business, both as a hobby and as a way to turn a profit. As a general rule the more rare a coin is the more it's worth, so what's the rarest coin ever? It's a debatable subject as not all experts always agree, but if the Double Eagle isn't at the top of that list it's sure near it. Back in 2002 the only Double Eagle coin left to be in private hands (or so everybody thought) sold for $7.9 million dollars.

Other rare coins include the Double Eagles smaller cousin the Quarter Eagle, and then the Brasher Doubloon, and the Eagle. More for fun then there's always the world's biggest coin, valued at $2 million+ (it's weights over 220 pounds and is the size of a pizza -- that would be a fun delivery!).

Good luck searching those pockets!

The news last week of a $10 gold coin that sold for $5 million is particularly interesting because the date on the coin is not the date it was minted. The Eagle coin is stamped 1804 but was created in 1834 at the Philadelphia Mint for Andrew Jackson as a diplomatic gift. This coin has some pretty fast appreciation, it sold for $1 million in 2003 and then for $2.47 million in 2005. There are just four of them out in the world.

I wonder what is it about coins that makes the prices rise. In part it is because they are a tangible record of history but I suspect the real reason is something else. As David Albanese, the president of Albanese Rare Coins, the dealer of the coin, reported both the buyer and seller are "northeastern United States entrepreneurs who have been collecting coins since they were young boys." I think this is why some coins sell for such high prices. Many other collecting hobbies take root after one is established in the world, wine, art, jewelry and watches, the love of those often develop later in life. But so many young boys and girls are given coins as gifts, thereby establishing a lifelong love of numismatics.

People buy and sell expensive things all the time, but here's an interesting story of how a dime worth $1.9 million dollars traveled across the country from its old home in San Jose to its new home in New York City. Who knew it was as simple as a guy in flip flops carrying it there in his pocket? Well I'm sure that guy, John Feigenbaum, would say it was anything but simple. He dressed in flip flops so he wouldn't attract undue attention, tried to fly coach (but got upgraded to first class anyway), and didn't sleep a wink on a red-eye flight for fear of losing the precious cargo somehow.

The 1894-S dime is one of nine known to have survived from only 24 minted in San Francisco that year. Of course the new owner, who is choosing to remain anonymous, has no intentions of doing anything with the dime other than keeping it stashed away in his vault as an investment for the future -- after spending a few minutes admiring it, of course.

The US Mint is aiming to target both collectors and investors with their newest release: a 24-karat gold coin. It contains one ounce of 99.99% pure gold and is cast as a tribute to the popular buffalo-head nickel that was in circulation during the 1930s. The coin will be minted as a $50 piece, though it will be worth, and sold, for more. Two versions of the coin will be available: a bullion coin for investors, which will be sold to authorized buyers for coin shops, banks and other financial institutions, and a proof coin, aimed at collections. The proof coin has a higher quality strike and finer finish, both of which will add to the physical appeal of the coin over simply the gold it is made of. 300,000 proof coins will be made and sold at an initial price of $875 per coin.

Interested buyers can purchase the proof coins beginning Thursday by going to the US Mint's website.
