Celtic Coin Hoard

Metal detector hobbyists have discovered a hoard of Celtic coins in the Channel Islands. And it's a big hoard.

Imagine digging a hole in the ground and uncovering 50,000 coins. Oddly, they were fused together in a solid block weighing three-quarters of a ton. Archaeologists needed a crane to lift this tangled mass.

Initial assessments date these coins to around the year 50 BC -- roughly the time of Julius Caesar’s conquest of Gaul. If accurate, that would make them over 2,000 years old, as explained in this Coin World article:
Hoard yields thousands of Iron Age coins

Why does this fascinate me so? I suppose it’s because I've always dreamed of uncovering.... hidden mysteries. As to what those might be, I'm quite flexible. It doesn't have to have monetary value. No, the hidden mysteries I'm interested in include the forgotten, the abandoned, or things that are just plain hidden and old. A few examples:

• The Kecksburg Incident
• John Michell
• Infiltration: places you're not supposed to go
• Disused stations on London's Underground
• Secrets of Grand Central Station
• Abandoned mines
• Carney Mine, Unity Township, PA
• Stuff that's gone
• The underground stream

Sadly, hidden mysteries are tough to locate in Las Vegas, even with the most powerful metal detector. Yet this sort of thing happens regularly in England. For example, the Bredon Hill Hoard is described here: Metal detectorist makes find of lifetime with hoard discovery
