Quote from: <k> on April 03, 2014, 07:38:14 PMThe 5p is already small, so I wouldn't change it. According to Royal Mint guidelines, a 3mm difference in diameter between similar coins is acceptable, but you mustn't go below that. Such a difference is easily discernible by sight and touch, so 18mm for the 5p and 21mm for the 10p would work perfectly.

Quote from: <k> on April 03, 2014, 07:17:25 PMI like your ideas, but the current 10p is 24.5mm in diameter - way too large for its current value - compared to 18mm for the 5p. I would therefore reduce the 10p to around 21mm. Our coins are generally too large and heavy: pound coin too thick and heavy; 2 pound coin too wide. From this point of view, I prefer the euro system (shock, horror!). From the design point of view, smaller coins offer less scope, but utility and cost should take priority.
