If you are pushing the coin across the table at a constant rate, the friction of the table and the horizontal force of your hand pushing are equal, and the coin itself moves at a constant rate.

In both cases, the gravitational downward pull of Earth is equally but oppositely resisted by the upward push of table on the coin.
