+\section{Fees per coin} \label{sec:fees:coin}
+
+Payments with Taler are always made using coins. Each coin has a specific
+denomination, and an exchange will issue coins in different denominations (in
+the same currency). The fees per coin depend on the operation and the
+denomination.
+
+The primary fee to be paid is a {\bf deposit} fee that is
+charged whenever a coin is fully or partially deposited
+into a bank account or another wallet.
+
+A secondary fee to be paid is a {\bf change} fee that is
+charged whenever a coin partially spent and change must
+be rendered.
+
+Coins also have an {\bf expiration} date of approximately {\bf one year}.
+After the expiration date, coins become worthless. Wallets that are online
+{\bf three months} {\em before} a coin expires will automatically trade any
+such coins for one or more fresh coins with a later expiration date. This
+process is also subject to the {\bf change} fee.
