Silver Ounce 2015 Britannia, Bullion, Coin from United Kingdom - detailed information

The obverse of the coins shows the crowned mature head of Queen Elizabeth II facing right (her effigy known as the "Fourth Portrait"). The Queen wears the "Girls of Great Britain and Ireland" diamond tiara, a wedding gift from Queen Mary (Her Majesty's grandmother) in 1947 - which she also has on the Machin and the Gottwald portraits.

In small letters below the head, the artist's initials IRB (for Ian Rank-Broadley).

Around the effigy is the monarch's legend: ELIZABETH ' II ' D ' G REG ' FID ' DEF ' 2 ' POUNDS '. Translated from Latin: Elizabeth the Second, by the Grace of God, Queen, Defender of the Faith, followed by the value and denomination in English.

The border is "crenellated" (toothed).

At centre, the standing figure of Britannia - the female personification of Great Britain, facing left, with flowing robes, wearing a crested Corinthian helmet pushed back to reveal her face. She is holding a trident in her right hand; her left hand rests on a shield decorated with the cross of the Union Jack, and holds an olive branch. She is standing on a rock, with sea waves in the background.

Around, interrupted by the trident, the inscription ' BRITANNIA ' 2015 ' 1 oz ' 999 ' FINE ' SILVER '.

The artist's surname NATHAN (Philip Nathan) is in relief in small letters on the rock under Britannia's feet.

The regular coin (with smooth surfaces) seems to be listed in Spink twice, under BF2C and BF3.

The Royal Mint gives "Silver £2 1 Oz Brilliant Uncirculated" but does not specify a breakdown by variety. It lists mintage of 2,870 - unclear for what.

The majority of coins have a textured background on both sides.
