Mark Carney, governor of the Bank of England, has met with First Minister Alex Salmond to discuss the implications for currency in an independent Scotland.
Mr Salmond said the meeting had gone "extremely well" and said he expected "technical" discussions between the bank and the Scottish government to continue ahead of the independence referendum.
What do voters think? BBC Scotland asked passers-by in Edinburgh what currency they thought should be used if there was a Yes vote.
