This is a typical one yen coin. In today's exchange rate, it worth less than one U.S. cent ($0.0098, to be exact). But recently, a one yen coin sold in Japan for the price of a car. Why? Well, it was anything but typical.

As you can see below, the coin that sold for well over twenty grand was a minting error—a pretty big one. Via Yahoo! Japan, here are the front and the back:

On one side, for instance, all that is visible is the word "Heisei" (平成). Note that in the Japanese calendar, we are currently in the Heisei Era, which began in 1989 with the new Emperor. The coin in the top photo reads "Showa" (昭和), referring to the Showa Period (1926 to early 1989).

Since errors like this typically do not enter circulation and because there are collectors with loads of cash, the auction received 153 bids, before topping out at 2.8 million yen—which is $27,499.


As website Naver points out, in the past other error coins have fetched high dollar (er, yen) in Japan. While I'm no coin expert, this latest auction seems to be staggeringly expensive, though.

In the past, error 50 yen coins, which should have circle in the middle, have gone for a couple thousand dollars.

Here are the front and the back of a fifty yen coin, which is worth about 49 cents:


And here are error coins, which went for 242,000 yen ($2,380) and 359,000 yen ($3,530), respectively.


Hope people working at the mint don't start making these on purpose.
