Copyright protection is required in the US Constitution (among other documents) to be for a limited time, so protection must expire.
The laws have changed many times over the past 200 years, so you would need to know when a particular work was published before you can figure out when its copyright would expire, and whether other factors are involved (type of work, nationality of author, copyright notice and renewal, etc).
You should also know that some works have no copyright at all and never did.
