Simply because they exist in their natural state. Most elements are naturally found in compounds (ores, minerals) and must be processed to access the actual elements.
Copper and Silver are both elements. However the copper and silver objects you find in everyday life are unlikly to be 100% pure copper or silver. These objects will be made with copper or silver alloyed to other metals to improve its properties or decrease its cost.
Gold, silver, and copper, are among a few that appear as native elemental metals. Most others have combined with other elements.
The elements Copper (Cu) and Silver (Ag) may be in the same group, but they are completely different elements. This means they have a different amount of electrons. Copper has 29 electrons, wheras Silver has 47.
Several high melting elements may be mixed with molten silver as Lead, Copper, Gold.
They are transition elements. Group 11 contains traditional coinage metals of copper (Cu), silver (Ag), and gold (Au).

silver, copper. copper can be replaced by germanium, zinc, platinum

The metals silver, copper and nickel are elements. It is brass that is an alloy, and copper and zinc are what make it up.
The elements platinum, silver, and copper are similar to gold.
Not known; some chemical elements as gold, copper, silver, mercury, sulfur, carbon, etc. are known from prehistoric times.
Gold, Silver and Copper belong to the native elements mineral group.
no way to say as it was known before earliest civilization.
Several high melting elements may be mixed with molten silver as Lead, Copper, Gold.
silver and clad(clad is a mix of silver and copper).
