The discovery of a tiny silver coin has had a big impact on archaeologists studying medieval York, England.
The sceat, minted in York in the early 9th century, is in such good condition, that it must have been minted - and dropped - near York Minster, where the coin was found, proving the wealth of the medieval city. (photo)
The coin was found during excavations for a new elevator at York Minister. During the excavation, concrete from the 1960s was removed revealing "human remains spanning centuries, broken, carved stone from many earlier periods of the building," and Roman brick, possibly used by Victorians as backfill.
