/** FIXME: This can be retrieved from the Denomination? Do we need this?
* (Yes, it can be derived from coin's denomination, but the extra
* lookup/indirection also costs and is inconvenient. And when
* checking signatures and balances, do we really always want this
* extra step of going to the denominations? (#3828)
*
* Melting fee charged by the mint. This must match the Mint's
* denomination key's melting fee. If the client puts in an invalid
* melting fee (too high or too low) that does not match the Mint's
