From Old English ‘sceat’ that translates to money or property. In Old Dutch it means treasure and Old Norse it means tribute. See Merriam Webster.

A small thick coin of silver. Minted the first time by the Merovingians by the seventh and eighth century. Mainly found and mostly used in Francia, England, the Low Countries and Denmark.

Many sceattas have been found over the years, especially by metal detectorists. Most coins do not have any markings on them, but there are those with runic letters, as well as animals. See Encyclopaedia Britannica.
