Imagine your fortune wonders when you sell your 1 yen coin for a total of 2.8 million yen. That's what happened at a Yahoo Auction yesterday with the winner paying 2.8 million yen. I'm going to look for defective coins right now.

There's apparently a demand for such things, and avid and hardcore coin collectors will bid tons for these things. The coin in question doesn't just have a simple manufacturing error on it, such as a slight displacement in the design, it has the era "Heisei" and a "1" on the deformed aluminum coin.

There were a total of 153 bidders, with the auction price jumping to 300,000 yen immediately after bidding started. Three individuals bid over 2 million yen, and it ended at 2.8 million. Check it out below:
