First off, Scarlet Devil Mansion.

Elder sister on the gold coins, younger on the silver...

She's been giving them out as gifts, so there are some going around

but their circulation on the actual market is close to zero.

And then there's this.

A deposit note from Myouren Temple.

Let me see...

"Counterfeiters go to the Hell of Avici"?

The Mansion's coins are one thing, but isn't this just a piece of paper? It's not an amulet, right?

Right.

Originally, wealthy villagers started depositing their money at the Temple.

There's no burglar who'd dare enter the demon priestess' youkai temple, after all.
