Electrum being a precios alloy [Risolto]

When searching coins with extra filter “Composition: Non precious”, hits with “Electrum" alloy are also displayed. This naturally occurring alloy of gold and silver does not fit in here.

Hello,

Thank you for the suggestion. Electrum should definitely be considered as precious in the search, so I changed that.

Here is the full list of what the search engine considers as precious: silver, billon, gold, electrum, platinum, palladium, iridium, rhodium, ruthenium.

Electrum is mostly a naturally occurring alloy mainly of both gold & silver.

The very first coins were struck in Electrum.

Aidan.

thanks!
