Lien, Currency Equivalent

Hello! Though I have been watching the RWBY series for a while now, I have trouble making sure on how much is each product and what could be the real life equivalent.

My main question is: What is Lien's real life equivalent?
To help, I have a few products to try to compare and understand.

1lb of oranges

1 Shotgun, Standard with Iron Sights

1 World History Textbook

1 bowl of Ramen

A fresh pair of street shoes

And a total cost to buy a well-maintained classic muscle car.

I understand if someone else may have asked this before, but I wanted to make sure that I can make fair exchanges and prices with other players.

Thank you for taking the time to read this!

I am uncertain, things on the site do have set prices based on our payout, but I always took it more like yen than dollars or pounds. As in 100 lien = 1 dollar rather than 1 lien.

I would think so as well that Lien is something close to Yen. I think I might figure it out from here, thank you very much!
