Anglo-Saxon coin worth £200,000 unearthed by a lucky metal detectorist in Wiltshire

According to Peter Preston-Morley, Head of Coin Department at Dix Noonan Webb, the coin was minted from high-purity gold, with very few, natural impurities.

An analysis carried out earlier in June this year shows trace amounts of silver and copper – 2.8 and 0.6 percent respectively.

Mr Preston-Morley said: “This composition is consistent with that of natural gold which has been neither refined nor artificially alloyed.

“Perhaps of more significance, the composition of the Ecgberht mancus falls within the same range as other medieval coins reported by Dr Gareth Williams and Dr Michael Cowell in 2009.”

Gold of such purity is very easy to work with but is also much easier to suffer damage and wear and tear.
