This is the indicator from Planet Money.

Kristen Carter is the owner of the Busy Beaver button Company in Chicago.
She makes pin back buttons.
You know, the kind that you might put on your backpack or your jean jacket.
And if you wanted to pick a button friendly slogan to describe the company, it could be made in the USA.
Like almost everything is within 100 miles.
You know, like we try to be as local as possible for everything.
So for example, Busy Beaver gets its steel from Indiana.
That steel is then sent to Chicago where it's coated with tin that helps.
Stop corrosion and rusting.
Okay.
Is that why you choose it for your buttons?
Yeah, that's why everyone uses it.
That's the advantage of tin plating.
Button makers have been using tin plate for over a century.
Kristen also curates the Button Museum in Chicago.
And she's got a tin plate button in her collection from 1892.
