Of course they did.
No, they did not, again nobody would use pennies and pounds together as a single scale, such scaling is metricated thinking.
You can count the value of the old coinage by weighing it, you really think that such a system was an accident?
I mean, I'm familiar with the history so I know 12 of 20 was a deliberate choice, but if you don't want to read into it, ask yourself if that's plausible.
Which nobody considered for a single seconds. Nobody was counting the number of pences in a pound at the time, these were not sensible scalings of values. Instead you had what was essentially 2 different scales: the pence scale (which topped out to the shillings) and the pounds scale (which bottomed out at the shilling)
> You said it yourself, 60 pence to a crown
I also said that it had no actual relevance.
> Decimalization was probably the right call in an age of calculators and computers, same with the metric system, but the old LSD system and imperial units existed for a reason, which is easy divisibility into convenient fractions.
They mostly existed because they were direct offshoots of the carolingian currency system. After all Roman currency had been decimal (or a mix of decimal and binary) before it devolved, and Russia began the movement of re-decimalising currencies.
