I'm even dafter (is that a word?)
in the US, we get given rolls to roll our coin in by the bank, like .50 pennies, $5 dimes, $10 for quarters, etc. In fact many US banks won't even take your coin unless it's rolled (unless they have a counting machine). I've noticed businesses in the UK open up little plastic bags of change instead of rolls, so how do you deposit coin? Do you ask for the bags or just use regular sandwich bags? Do you hand them your jar and let them weigh it?
