The Royal Mint has never produced a Quarter-Sovereign coin until 2009. There has never been a need for a Quarter-Sovereign coin, since the Crown (Five Shillings) did the job and, after decimalisation, the 25 Pence coin to a lesser extent. The recent interest shown in Quarter-Sovereign coins seems to stem from a disreputable somebody claiming to have scooped the world market on a finite number of coins only available to them and, mysteriously originating in another country.
The Royal Mint releases new coins regularly, but most are for the collector or investment market. The latest of these coins would be the gold Quarter Sovereign first issued in 2009. The latest general circulation coins were those first issued in 2008 which, when positioned correctly, depict the Royal Shield. The One Pound coin shows the entire Royal Shield.
