Details of the coin can be found here at the Spink Auction Page.
For one lucky detectorist back in September of this year, he set off out on a hunt just like I expect we all do, dreaming of a nice find, and boy did his dream come true. He found the gold coin above, it was only about 4" deep so any machine would have found it. That coin yesterday sold at auction for £36,000. What a result.
Good news for the finder and good news for the landowner. What a happy Christmas they'll have.
