Is the water rusty color? Or is the rust color on the pool finish - plaster or vinyl or fiberglass?

No. Water is actually a major cause of rust.
Copper doesn't rust
Copper and zinc-plated pennies do not rust, because they're not made of iron. The only American pennies that could rust were the steel cents struck in 1943. You might believe that a penny is rusting but instead it is corroding! Yes, it does not rust it just corrodes.
It depends on what metals the coin is made from!
The oxygen dissolved in the water combines with the iron to form iron oxide, or rust (Fe2O3H2O).
