As far as I can tell online, 100 million Iranian Rials is about $73. And there are ten toman to a rial. So maybe it's more like $730. But I also found this on a reddit thread in /iran

Officially, 10 Rials is one Toman. But very unofficially, toman can erase as many zeros as you want based on the context. Talking about a bottle of water? 2 toman means 2000 tomans. Talking about something a bit more expensive, like a rug? 20 tomans means 20 000 000 tomans. Talking about something very very expensive like a house? 4 toman means 4 000 000 000 tomans.

Since this is a large number and it's in the news, that probably doesn't apply. It sounds more like street vernacular. But it tells me that I really don't know anything about Iranian money.

Wrong way, 10 Tomans to 1 Rial means 100,000,000 Tomans = 10,000,000 Rials = $7.30

Nevermind, I read the other comment wrong.
