Now there may be those who accuse me of being a bit literal here, but I found the ending unsatisfying.

Why did the REDACTED fall from the REDACTED at exactly that moment? Did Lance and Andy SEE them fall? How much were they worth? Were they declared treasure trove, in which case how much did Lance and Andy get each? Did they share it with the other members of the metal detecting club, including the two temporary members? How much work was required on Andy's house? Is he qualified to tackle the more technical trades? And now I come to mention it, wasn't Lance already rich from his find at the end of series 2?

Lazy writing, if you ask me. Shakespeare would have had a big denouement, when everything got explained.
