How much is a buck worth in stirling?

The value of a buck (often referring to one US dollar) in British pounds sterling fluctuates based on current exchange rates. As of my last update, the exchange rate typically hovers around 0.75 to 0.85 GBP for 1 USD, but it can vary daily. To get the most accurate value, it's best to check a reliable financial news source or currency converter for the latest rates.
