[QUOTE="user 4386, post: 592606, member: 4386"] "Gold" can contain 50% silver in some cases and is never 100% (although you can get up to 99.7% with some supergene gold). It is a similar issue with silver. "Electrum consists primarily of gold and silver but is sometimes found with traces of platinum, copper, and other metals. The name is mostly applied informally to compositions between about 2080% gold and 2080% silver atoms, but these are strictly called gold or silver depending on the dominant element". And you are not selling something with a defined value, just an object that someone is willing to buy (although their offer if they are professionals would be based on a guess about % gold and its appearance and size). You can't generalise about the purity of gold based on the State - it tends to vary with the type of deposit, and whether it is primary or secondary (as gold gets purified near surface by weathering). For example, some gold in Victoria at St Arnaud would exceed 50% silver but most in the central goldfields is 2-8% silver, usually 2-3%, unless it is supergene (secondary) where I have found 99.7%. However I have had closer to 20% silver around Woods Point [/QUOTE]
