 What are Currency chests?

Currency chests are branches of selected banks authorised by the RBI to stock rupee notes and coins.

• The RBI offices in various cities receive the notes from note presses and coins from the mints. These are sent to the currency chests and small coin depots from where they are distributed to bank branches.
• The RBI has set up over 4,075 currency chests all over the country. Besides these, there are around 3,746 bank branches that act as small coin depots to stock small coins.
