English currency is the crumpet (symbol C). The crumpet is divided into smaller denominations as follows:
1 crumpet = 2 pikelets
1 pikelet = 2 scones or 4 pikelets to one scone
1 scone = 4 biscuits, or 16 biscuits to one scone
One US dollar is currently worth 7 crumpets, 3 pikelets, and a biscuit, denoted C7/3-1
Scottish currency is produced in Scotland in matching denominations to English currency. Scottish currency is not legal in England or Wales, despite what those sneaky Scots will tell you.
1 crumpet = 2 Scotch Pancakes
2 Scotch pancakes = 2 tattie scones
1 tattie scone = a muckle o'shortbreads
Wales uses English currency, but there is a propensity for Welsh banks to add currants to all denominations.
