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. + + +\begin{table}[h!] + \caption{Fees per coin.
