As of 11th of December 2009, Copper is more valuable than zinc.
According to the London Metal Exchange, Copper is worth $6.87 / kg and Zinc $2.29 / kg.

A zinc penny would dissolve in phosphoric acid, not a copper penny. Zinc reacts with phosphoric acid to form zinc phosphate and hydrogen gas. This reaction does not occur with copper, as copper is a more stable metal and does not react with phosphoric acid in the same way.
Zinc is more reactive than copper sulfate. When zinc is placed in a solution of copper sulfate, a displacement reaction occurs where zinc displaces copper from the solution, forming zinc sulfate and copper metal.
Copper is more reactive than zinc because copper has a lower reduction potential, making it more likely to lose electrons and undergo oxidation reactions. In addition, copper is closer to the top of the reactivity series than zinc, indicating its higher reactivity.
Yes, the reaction between zinc and copper sulfate is a single displacement reaction. In this reaction, zinc displaces copper from copper sulfate to form zinc sulfate and copper. The more reactive zinc replaces the less reactive copper in the compound.
Not under conditions of normal temperature and pressure, because the reactants and products are all solid, or in practice more often all dissolved in a solvent, and stable under such conditions
copper II compounds are more stable because it is hard
Nitric acid can dissolve copper but not zinc because it forms a complex with copper that is more stable than with zinc. This allows the nitric acid to selectively dissolve copper while leaving zinc unaffected.

The two do not react. Zinc is more active than copper and thus copper can not displace zinc.
Zinc
Because zinc is more reactive than copper.
it is because zinc is more reactive than copper. thus it can replace copper from its compound. displacement reaction is the reaction in which the more reactive element replaces the less reactive element from its compound. hence zinc is replacing copper from its compound. Obviously it is a displacement reaction.
zinc is more reactive than copper hence it displaces the copper in copper sulphate solution to become zinc sulphate and copper metal is formed
Copper rods cannot separate zinc from zinc sulphate because copper is less reactive than zinc, and cannot separate the zinc which is more reactive than copper. If you get copper sulphate and add some zinc to it, you will see solid copper appearing on the bottom of the test tube... The copper cannot push out the zinc from the solution and take its place.
Copper is more reactive than zinc because copper has a lower reduction potential, making it more likely to lose electrons and undergo oxidation reactions. In addition, copper is closer to the top of the reactivity series than zinc, indicating its higher reactivity.
copper and zinc both are conductive materials but as copper is in lower position than zinc in electromotive charts zinc is more than copper but other material properties like corrosive force,strength are better for copper. so for daily use copper is better than zinc.
