Can someone please help ID and date? Copper coin, square hole, and I assume Chinese. I just don’t know how to date the coin.

Chinese coins like this, called 'cash coins', are dated only to the span of years of the emperor's rule, no tighter.
Your coin may have looked like more like this originally:[h=2]Emperor KAO TSUNG
AD 1736-1795[/h][h=3]reign title: CH'IEN-LUNG, AD 1736-1795[/h]
