By "the" penny, I'm assuming that you mean a penny that has been treated with zinc and sodium hydroxide, and then heated over a flame.
To remove the brass plating, you can create friction on the surface of the coin that wears it away, reverting it back to its original copper color.
Gold, definitely. How about fixing this question as to what type of "brass" There is Yellow brass 60% Copper 40% Zinc and the more common red brass 85% copper and 15% Zinc then there is Muntz metal and Bronze thus BRASS = COPPER as there is NO gold content in "Brass"
because brass is generally tarnish resisant so it does not discolours easily and also because brass is not such expensive as copper <<>> The pins are make of brass because it is a harder metal than copper and will wear better through use over its lifetime.
Brass is an alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. Although forms of brass have been in use since prehistory, its true nature as a copper-zinc alloy was not understood until the post medieval period because the zinc vapor which reacted with copper to make brass was not recognized as a metal. The King James Bible makes many references to "brass". The Shakespearean English form of the word 'brass' can mean any bronze alloy, or copper, rather than the strict modern definition of brass. The earliest brasses may have been natural alloys made by smelting zinc-rich copper ores.

This might be possible with a ton of vinger or lemons, and a lot a scrubing. I am not a 100% sure if it coule happen but it is worth trying. That was a great question. That would be a great experiement to try.
Brass is the alloy of copper and zinc.
Both brass and copper are conductors.
Copper is cheaper than brass.
Brass is mainly an alloy of copper and zinc. Some alloys do have small amounts of arsenic added also.
Depends on what the usage is do you want YELLOW Brass 60% Copper 40% Zinc Or do you want RED BRASS? 85% Copper 15% Zinc
Brass is an alloy made by combining copper with zinc. It is not a nonmetal; it is a metallic alloy.
Both these alloys contain the common metal,copper
Zinc and Copper Copper and zinc make up the mixture (alloy) brass.

No, copper and brass do not have the same density. Copper has a density of around 8.96 g/cm³, while brass, which is an alloy of copper and zinc, has a density that varies depending on the specific composition. Generally, brass has a lower density than copper due to the addition of zinc.
there are many combinations of brass/copper/zinc. High brass for example has 65% copper and 35% zinc. Nickel brass has 70% copper and 24.5% zinc with 5.5% nickel Prince's has 75% copper and 25% zinc
