Feast of the Silver Coin

The Feast of the Silver Coin was a religious celebration observed by worshipers of Nephthys, the Guardian of Wealth and Commerce within the Mulhorandi pantheon. The same holy day was known elsewhere in Faerûn as the Feast of the Moon.

Description
During the Feast of the Silver Coin, priestesses of Nephthys celebrated a somber day-long event where they gave thanks to their goddess and tithed half of their wealth at day's end.
