It’s right there in plain language. Gold and silver.

You're missing one important qualifier: Coin

And above that, there is the prohibition of states "coining" money.

Most they can do now, is stop taxing sales of gold and silver within their state, according to how I read it.

I don't like it, but isn't that what the Constitution says?
