Avagadro's number is the number of molecules on a mole of any materoal. Assuming that the one cent piece is made of copper (it is actually cupro-nickel), and it weighs 5 grams, it would contain, say one twentieth of a mole of copper. Therefore, the number of atoms would be one twentieth of Avagadro's number.
Now, Avagadr's number is a BIG number: 6.023 E23. That's roughly 6 with 23 noughts after it. So therefore, our one cent piece would contain one twentieth as much, or 3 E22. That's 3, with 22 noughts after it. A VERY large number of atoms.

Electrons will come and pass, yet in any different case i could assume something of it to be the comparable as initially the place the coin has remained intact. The debris that make up the coin are no longer in any actual fluctuating device and so are unlikely to get replaced except on purpose.

It depends upon what year the penney was made in.
Between 1971 to 1991 they were bronze
and then plated steel until 1998
and after that my book just says
"non-magnetic.

Find out what its made of (I would assume mostly copper like the US, but I am not sure).
Find out the molar weight of that substance.
Weigh the coin.
Do the math.

Hi
It is calculable and it would go into many billions
