Current scores:

2 points to doubleshuffle.
10 points to Bilbo1967.
2 points to Bookpossum.

Still to get:
1. In what year did the UK first move towards decimalisation of its currency, and how?
2. Goods in the UK must be sold using metric measures. Well, almost. One point for each exception.
Beer and Milk have been given. Any others?
3. How much were the following in old (UK) money and new money?
Groat still to be found.
4. And as an apology to US members for the UK-centric nature, what's the largest value coin it has ever been proposed that the US Mint should issue?
5. And as an apology to everyone else, what's the currently issued lowest-value coin in the world?

Since these have obviously proved trickier, I'm going to increase the available points.

1: 3 points
2: still 1 point for any left
3: 2 points for each of the Groat's old and new values.
4: 4 points
5: 5 points.
