Two Pound Coins

I only talk about this because today I was given four of them. I bought a sandwich for £1.99 and as if it isn't bad enough that I was given four two pound coins in my change, when I opened the sandwich, the bread was wet. I didn't buy it from one of those gourmet places, it was just a shop. But considering that I could have made a better sandwich myself in about ten seconds, for £1.99 you at least expect the bread not to be the slimey consistency and colour of someone's flesh who has just been dredged out of a lake by police frog-men after about two months.
So I am walking about with a pocketful of coinage that is comparable to carrying a packet of digestive biscuits made of metal.
The inclination is to just spend them as quickly as possible. Offload a bit of weight.
They are strange, the two pound coins. Why? Those of you older enough to remember, or those of you of a Scottish persuasion, may remember the One Pound note. I liked One Pound notes. I think we should bring them back, and scrap 1p and 2p coins altogether while we are at it. They are a complete waste of time and they are ugly and stupid too. Particularly the 2p coin. Why is it so big? It's bigger than a 5p, a 10p and a 20p. That makes no logical sense. You can't use either of them in vending machines, and at any given time about half of them are out of circulation, either languishing in jars in people's bedrooms or down the back of sofas, or dropped in the street, where they are deemed so worthless that not only do the people who drop them not feel it is worth the effort of stooping to pick them up, even the most desperate beggars seem to ignore them. The city streets are not paved with gold, they are paved with 1p and 2p coins that nobody wants.
But I am getting off the point. When they had One Pound notes, there was never felt a need to have Two Pound notes. We think decimally. You have units, and then things work in increments of ten. Hence one pound, ten pounds, twenty pounds and so on. Five pounds seems okay, as if you are buying something slightly more than a pound, but a lot less than ten pounds, they make sense.
Years ago you used to be able to withdraw five pounds from a cash machine, but that is by the by.
But having something the size of a Wagon Wheel that is only worth two pounds, and is for some reason, despised by bus drivers (and vending machines, by the way) seems to me like folly.
Here is another thing about the Two Pound coin that I bet you haven't noticed. Its design is flawed.
On the opposite side from the Queen's head is a graphic of nineteen cog wheels arranged in a circle. Now presuming that the cogs are supposed to turn each other, an odd number of cogs would not work. Each cog turns the one next to it, so in engineering terms this arrangement wouldn't work.
