From c. 1124 until 1709 the coinage of Scotland was unique, and minted locally. A wide variety of coins, such as the plack, bodle, bawbee, dollar and ryal were produced over that time. For trading purposes coins of Northumbria and various other places had been used before that time; and since 1709 those of the Kingdom of Great Britain, and then of the UK.
