The only two Roman coins I know of are:

  1. the as (plural asses), originally worth a pound of copper, but later worth much less.
    So, how many Roman asses could I have gotten with a pound of copper? Just one? Or would I have needed to offer silver or gold?

While the above is correct, there were other Roman coin denominations as well. Most were either far less common denominations, and/or appeared later in the history of the Roman Empire:

Antoninianus: Basically a debased (very low silver content–somtimes copper with a silver wash) denarius. Invented during the third century A.D.

Dupondius: A large bronze coin struck in during the time of the Early Empire (the Twelve Caesars)

Follis: Bronze coin. Don’t know it’s value, but it was more common in the later periods of the Roman Empire.

Quadrans: Very small bronze coin. Don’t know about it’s relative worth.

Quinarius: Small silver coin, 1/2 the value of a denarius.

Semis: Bronze coin. 1/2 the value of an as.

Siliqua: Small silver coin. Don’t know it’s relative worth.

There are others, too. But they aren’t coming to mind at the moment.
