VANCOUVER -- Chris Monk was scanning the ground with his metal detector near Pacific Spirit Park in Vancouver when he came across something unusual. His detector alerted him to something under the grass, so he started digging. Six inches down, he found an old coin. He put it in his pocket and took it home. Once home, he began cleaning the coin, and posted pictures of it in online metal detecting groups. In the online groups, members alerted him to the significance of the coin -- they told him it was an ancient Roman coin. “This coin dates back to before the middle ages and when you think about the journey it’s taken to end up in my hand, that’s something quite spectacular,” he said.
