From a 2007 article on Vermont coins:
Vermont Freedom Currency is a single pure silver coin worth 10 Credits.
A single coin is worth $10 with the State of Vermont for any service, fee or tax.
This assures Credits hold an established value for purposes of barter.
These coins would operate as a voluntary barter currency accepted by individuals and businesses that choose to accept them.
They are not legal tender and cannot be converted into dollars except by a mutually agreeable private-sector transaction, such as might be done through e-Bay or Craigslist.
