The government introduced the decimal coinage, BUT despite advice from banks, financial institutions and people with experience in these matters, blundered ahead by basing it on the £ instead of the 10/- (Ten shillings - HELLO 10 - decimal!!!!).
NO, "The Pound" is sacrosanct and that's what it must be - f**king wankers, which caused a lot of confusion for years, because it meant that now 20p. Is that 2/-? NO! It's DOUBLE THAT, it's actually 4/-. WHEREAS, if they'd listened to people in the know and based it on the 10/- (HELLO 10 - decimal!!!) 20p would be 2/-, 30p 3/- etc. etc. and you could then still call it a Pound if you wanted to.
It's all academic now of course, but millions were confused and many traders etc. used the anomaly to charge more. "Oh, that 20p is 2 bob (2 shillings) is it?"
"Yes, my love. Lovely cheap apples! Only 20p for 6"
I also remember the date so well, as it was my birthday.
