I have looked around for this for ages and for obvious reasons, would be a very efficient means of paying bills without HMRC taking a cut (as long as I can't be attacked for Tax evasion).
I have seen the one case in the U.S. where a fella paid his invoices in Gold and it turned out bad for him. But the sums involved were huge. Mine are on a far lower scale, and probably would be below the radar.
What does it actually mean for a a coin to be legal tender, I see that many of the UK bullion coins are valued with a face value that no way represent their intrinsic value. Does this mean that I can create contracts of the face value, and actually pay in intrinsic value.
For example, a quarter Oz Britannia has a face value of £25 but is actually worth around £300.
My contractual agreement will be in £25, but I pay in 1/4 oz gold bullion. Is this legal?
