This BBC report is unintentionally hilarious:
Experts say the collection of 1,500 gold and silver pieces, which may date to the 7th Century, is unparalleled in size and worth "a seven figure sum".
Worth a seven figure sum, eh? How about "priceless," instead? It's rather like saying a lost child was found wandering the streets and "experts say his organs might fetch tens of thousands of dollars on the open market."
