Question: What is featured on the British decimal twenty pence coin that in banner form is know as the "Royal Standard"?

full_context: Document 1: Monarchy of the United Kingdom: The monarchy of the United Kingdom, commonly referred to as the British monarchy, is the constitutional monarchy of the United Kingdom, its dependencies and its overseas territories. The current monarch and head of state, Queen Elizabeth II, ascended the throne on the death of her father, King George VI, on 6 February 1952.
Document 2: Two pence (British decimal coin): The British decimal two pence (2p) coin – often pronounced "two pee" – is a unit of currency equaling two one-hundredths of a pound sterling. Its obverse has featured the profile of Queen Elizabeth II since the coin’s introduction on 15 February 1971, the year British currency was decimalised. Four different portraits of the Queen have been used on the coin, with the latest design by Jody Clark being introduced in 2015. The second and current reverse, featuring a segment of the Royal Shield, was introduced in 2008.
Document 3: British royal family: The British royal family comprises the monarch of the United Kingdom and her close relations. There is no strict legal or formal definition of who is or is not a member of the British royal family, and apart from Queen Elizabeth II herself, different lists will include different people. Those who, at a time in question, carry the style His or Her Royal Highness (HRH), and any styled His or Her Majesty (HM), are normally considered members, including those so styled before the beginning of the current monarch's reign. By this criterion, a list of the current royal family will usually include the monarch, the consort of the monarch, the widows of previous monarchs, the children and male-line grandchildren of the monarch and previous monarchs, the children of the eldest son of the Prince of Wales, and the wives or widows of the monarch's and previous monarchs' sons and male-line grandsons.
Document 4: Royal Arms of Scotland: The royal arms of Scotland was the official coat of arms of the King of Scots first adopted in the 12th century. With the Union of the Crowns in 1603, James VI inherited the thrones of England and Ireland and thus his arms in Scotland were now quartered with the arms of England (which was itself quartered with France) with an additional quarter for Ireland also added (the arms would continue to alter in later years). Though the kingdoms of England and Scotland would share the same monarch, the distinction in heraldry used in both kingdoms was maintained. When the kingdoms of Scotland and England were united under the Acts of Union 1707 to form the United Kingdom of Great Britain, no single arms were created and instead, the royal arms as used in either Scotland and the rest of the United Kingdom would continue to differ.
Document 5: Twenty pence (British coin): The British decimal twenty pence (20p) coin – often pronounced "twenty pee" – is a unit of currency equal to 20/100 of a pound sterling. Like the 50p coin, it is an equilateral curve heptagon. Its obverse has featured the profile of Queen Elizabeth II since the coin's introduction on June 9th 1982. Four different portraits of the Queen have been used; the latest design by Jody Clark was introduced in 2015. The second and current reverse (as of 2017), featuring a segment of the Royal Shield, was introduced in 2008.
Document 6: British twenty-five pence coin: The commemorative British decimal twenty-five pence (25p) coin was issued in four designs between 1972 and 1981. These coins were a post-decimalisation continuation of the traditional crown, with the same value of a quarter of a pound sterling. Uniquely in British decimal coinage, the coins do not have their value stated on them. This is because previous crowns rarely did so.
Document 7: Ten pence (British coin): The British decimal ten pence (10p) coin – often pronounced "ten pee" – is a unit of currency equalling ten one-hundredths of a pound sterling. Its obverse has featured the profile of Queen Elizabeth II since the coin's introduction in 1968, replacing the two shilling coin in preparation for decimalisation in 1971. Four different portraits of the Queen have been used on the coin, with the latest design by Jody Clark being introduced in 2015. The second and current reverse, featuring a segment of the Royal Shield, was introduced in 2008.
Document 8: Monarchy of the United Kingdom: The monarchy of the United Kingdom, commonly referred to as the British monarchy, is the constitutional monarchy of the United Kingdom, its dependencies and its overseas territories. The current monarch and head of state, Queen Elizabeth II, ascended the throne on the death of her father, King George VI, on 6 February 1952.
Document 9: Fifty pence (British coin): The British decimal fifty pence (50p) coin – often pronounced "fifty pee" – is a unit of currency equaling one half of a pound sterling. It is a seven-sided coin formed as an equilateral-curve heptagon, or Reuleaux polygon, a curve of constant width, meaning that the diameter is constant across any bisection. Its obverse has featured the profile of Queen Elizabeth II since the coin’s introduction in 1969. Four different portraits of the Queen have been used, with the latest design by Jody Clark being introduced in 2015. The second and current reverse, featuring a segment of the Royal Shield, was introduced in 2008.
Document 10: Royal coat of arms of the United Kingdom: The royal coat of arms of the United Kingdom, or the Royal Arms for short, is the official coat of arms of the British monarch, currently Queen Elizabeth II. These arms are used by the Queen in her official capacity as monarch of the United Kingdom. Variants of the Royal Arms are used by other members of the British royal family; and by the British government in connection with the administration and government of the country. In Scotland, there exists a separate version of the Royal Arms, a variant of which is used by the Scotland Office. The arms in banner form serve as basis for the monarch's official flag, known as the "Royal Standard".
Document 11: Coat of arms of the Netherlands: The coat of arms of the Kingdom of the Netherlands was originally adopted in 1815 and later modified in 1907. The arms are a composite of the arms of the former Dutch Republic and the arms of the House of Nassau, it features a checkered shield with a lion grasping a sword in one hand and a bundle of arrows in the other and is the heraldic symbol of the monarch (currently King Willem-Alexander) and the country. The monarch uses a version of the arms with a mantle (Dutch: "Koninklijk wapen" ) while the government of the Netherlands uses a smaller version without the mantle (cloak) or the pavilion, sometimes even only the shield and crown are used (Dutch: "Rijkswapen" ). The current components of the coats of arms were regulated by Queen Wilhelmina in a royal decree of 10 July 1907, affirmed by Queen Juliana in a royal decree of 23 April 1980.
Document 12: Twenty pence (Irish coin): The twenty pence (20p) (Irish: "fiche pingin" ) coin was a subdivision of the Irish pound. It was introduced on 30 October 1986. It was first Irish decimal coin that was of a different size to the corresponding British coin, as the Irish pound had not been pegged to the British pound since 1979. Its last issue was in 2000, two years before Ireland withdrew its pound for the euro.
Document 13: Commander-in-chief of the British Armed Forces: The Commander-in-Chief of the British Armed Forces is a position vested in the British monarch, currently Queen Elizabeth II, who as Sovereign and head of state is the "Head of the Armed Forces". Long-standing constitutional convention, however, has vested "de facto" executive authority, by the exercise of Royal Prerogative powers, in the Prime Minister and the Secretary of State for Defence, and the Prime Minister (acting with the support of the Cabinet) makes the key decisions on the "use" of the armed forces. The Queen, however, remains the "ultimate authority" of the military, with officers and personnel swearing allegiance only to the monarch.
Document 14: Royal Banner of Scotland: The Royal Banner of the Royal Arms of Scotland, also known as the Royal Banner of Scotland, or more commonly the Lion Rampant of Scotland, and historically as the Royal Standard of Scotland, (Scottish Gaelic: "Bratach rìoghail na h-Alba" , Scots: "Ryal banner o Scotland" ) or Banner of the King of Scots, is the Royal Banner of Scotland, and historically, the Royal Standard of the Kingdom of Scotland. Used historically by the King of Scots, the banner differs from Scotland's national flag, the Saltire, in that its correct use is restricted by an Act of the Parliament of Scotland to only a few Great Officers of State who officially represent the Sovereign in Scotland. It is also used in an official capacity at royal residences in Scotland when the Sovereign is not present.
Document 15: Five pence (British coin): The British decimal five pence (5p) coin – often pronounced "five pee" – is a unit of currency equaling five one-hundredths of a pound sterling. Its obverse has featured the profile of Queen Elizabeth II since the coin’s introduction on 23rd April 1968, replacing the shilling in preparation for decimalisation in 1971. A smaller version of the coin was introduced in June 1990 with the older coins being withdrawn on 31st December 1990. Four different portraits of the Queen have been used, with the latest design by Jody Clark being introduced in 2015. The second and current reverse, featuring a segment of the Royal Shield, was introduced in 2008.
