Guldencoin might be the first non scam country coin as they have already acquired a sizeable merchant such as subway's, sure it's only 1 branch for now but that is more then any other country coin is offering at this stage.
It will be interested to see if more dutch merchants and especially subway branches adopt guldencoin on a more national scale, it also wouldn't surprise me if the Netherlands becomes the leading country for Crypto currencies with the dutch having a proud history in being in the forefront of modern economics and trade in the last 200-300 years.
The great thing about guldencoin is the price has been stable and no evidence at this stage that it was setup as a PnD scheme like 99% of the coins these days.
