What was the dispute over the form of National Currency between William Jennings Bryan and William McKinley?

Question

-was it about the Gold standard and coinage of silver?

Answer 1

"The supporters of silver coinage urged the federal government to buy large quantities of silver, issue currency based on it, and put 16 times as much of it in a silver dollar as the amount of gold in a gold dollar."

So Bryan wanted silver to be the nation's currency and not gold?

Answer 2

Right.
