Yes. Friction is the resistance between an object and the surface in which it is. When pushing the coin, an opposite force is pushing it the other way, because the forcce you apply to the coin is greater it moves but that doesn´t mean there is no friction.
IF your coin is a common-date coin, pour some baking powder into a bowl put your coins in it then add some quantity of water.......... after 15 mins your coins will look shiny and newBUT NEVER, EVER DO THIS WITH A VALUABLE COIN!!! Cleaning will affect the surface and accelerate any deterioration that already exists.
If you neglect air resistance, they'll hit the ground at the same time. This is a classic experiment proving that the force of gravity acts the same way on all objects. On the earth objects fall at an acceleration of 9.8 m/sec/sec, meaning their velocity increases 9.8 m/sec for every second they're falling. The same experiment has been done by people ranging from Galileo to American astronauts on the Moon. In reality, air resistance will have an effect on the speed and acceleration at which objects fall. All objects experience friction / resistance from air molecules, so anything that meets more resistance will fall more slowly. That's why a parachute lets a person fall more slowly than if they just dropped - its large surface area increases air friction. However, for similarly-sized items air resistance can be ignored because it will affect both the same way. A 5 rupee coin is larger than a 2 rupee coin so it may be slowed just a bit more. But if you did the same experiment in a vacuum the 2 coins would reach the ground at the same time.
It depends on what metals the coin is made from!

Gold plating essentially destroys the coin. While it might be technically possible, it would be destroying the details of your coin, especially if unprofessionally done. Cleaning coins also destroys the coin too.
After your finger stops pushing, there are two forces acting on the coin: gravity pulling it downward and the force of the table or surface pushing upward to support the coin and prevent it from falling.
3 forces gravity drag lift
A wet coin does not slide easily on a ramp because the water creates a layer between the coin and the surface, reducing friction. This layer of water prevents the coin from making direct contact with the ramp, which in turn reduces the friction force that allows the coin to slide.
When I slowly pulled the cardboard, the coin placed on top of the cardboard remained at rest but was dragged along with cardboard. Explanation: That is because, the coin was dragged by the force in the surface of the cardboard called friction.

The force that slows a spinning coin down is called friction. As the coin spins, it interacts with the air or any surface it comes in contact with, causing it to gradually lose its rotational energy and slow down.
The rolling coin likely slowed down due to friction between the coin and the floor surface, which creates resistance against its motion. As the coin rolls, the frictional force eventually dissipates its kinetic energy, causing it to slow down and eventually come to a stop.
because of air and mechanical friction which slows the coin eventually defeating the coins inertial force.
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.
no, it will float on the surface
The speed at which a penny or nickel moves when it is pushed along a surface will vary depending on the force applied and the friction between the coin and the board. In general, the speed will not be very high given the small size and weight of the coin.
Friction is a sticky force that appears when 2 objects rub against each other. If you push or pull slowly friction helps pull or push the tower along with the bottom coin. If you push or pull quickly, the coins still rub, but the friction force doesn't have time to get the stack moving. So the coin shoots out without pulling the tower with it.
