A \emph{coin} in Taler is a public-private key pair where the private
key is only known to the owner of the coin. A coin derives its
financial value from an RSA signature over the FDH
of the coin's public key. The exchange has multiple RSA {\em
denomination key} pairs available for blind-signing coins of
different value.

Denomination keys have an expiration date, before which any coins
signed with it must be spent or refreshed. This allows the exchange
