Coins as tokens

So I have been doing some work in this area and I am finding that one significant gap to overcome with issuing a coin is that the “coin” really needs to take on the role of a token such that it is its own closed medium of exchange among the members of the group using the coin.
Meaning, if you look at Bit Coin as an example, my current focus is on its lack of independent value for the user group to be able to exchange coins at a par value. As long as the “coin” is pegged to some governmental currency it is not truly an independent medium of exchange and is still vulnerable to outside market forces and speculators.
