The contrast with the introduction of the euro coin series is great. In that instance, the re-thinkers beat the traditionalist. Easy enough if you are dealing with many different traditions.
the resizing of the 5p and 10p actually occurred 5 or more years after the prediction. Given the low total mintages of those coins between 1981 and 1990/92, it seems clear that a change was needed. So why did it take till 1990 to sort it out?
I have no answer for that. I first saw various options presented in the Royal Mint bulletin (sent out to coin collector customers) of Christmas 1985. Then I waited, and waited, and waited. :-X
Maybe some of our members would like to say how they would design a totally new UK coin set from scratch, if they had a free rein to decide size, shape, metal, denominations and design.
Denomination | Approx. Diameter | Colour/Composition | Shape | Approx. Weight |
5p | 18mm | Red (Copper-plated steel) | Scalloped edge | 2g |
10p | 22mm | Red (Copper-plated steel) | Round | 4g |
20p | 20mm | White (Nickel-plated steel) | Heptagonal | 3g |
50p | 24mm | White (Nickel-plated steel) | Octagonal | 6g |
£1 | 23mm | Yellow/White (Bimetallic) | Round | 7g |
£2 | 25mm | White/Yellow (Bimetallic) | Round | 9g |
£5 | 28mm | White/Yellow/Red (Triimetallic) | Decagonal | 11g |
Any other thoughts on this or other suggestions?
I definitely think we should be looking for a circulating £5 coin

I don't really agree with the current philosophy that all coins must be as small and light as possible. Sometimes it seems that the only reason any coins are bigger than 25 mm and weigh more than 6-7 g is because of the physical impossibility of shoehorning a full range of denominations into the available spectrum (say minimum 17.5 mm). It always feels as if anything larger is made grudgingly.

I just looked at one of my 12-sided pound coins and remembered they were going to include the year on the edge. In fact, there is just a plain smooth edge where the year was going to be. When was this change decided on?
The apparent reeding is an optical effect, moiré (https://en.wikipedia.org/wiki/Moiré_pattern), resulting from low resolution.
The series has size differences of 1.5 mm between coins of the same colour. The number was chosen because it was scientifically determined that it is sufficient for the blind.
Short after they released that computer drawing (so very early in the process). It was very dumb of them to include that as they did not take into account that in future years the date in roman numerals would contain much more roman numerals and would likely no longer fit on the edge.
The minted trial pieces that were handed out to businesses did not have that edge lettering. The only piece that may ever have been minted with it is the trial strike that was minted by the Chancellor of the Exchequer at the Royal Mint in 2014.

By including the euro system, I am not comparing like with like. However, it was a logical system that was developed from a clean slate, and it shows how you can have a generally smaller and lighter system of coins.

Both Germany and the Netherlands had "copper" for the low value coins, but NL did not have brass.
I would criticise hertfordian's choices, because he has only a 1mm gap between four coins, and two round coins have only a 1mm gap between them. This would confuse blind people. So, I think my system is superior in terms of functionality, but his would look prettier than mine. If we had a forum poll, probably most voting members would choose looks over functionality. :-\
It's certainly harder than one would have imagined trying to come up with something from scratch! :-)
Mrs Thatcher and the chocolate money. :-X
