This is a fantastic set of coins, which you would have to pay almost £300 today JUST for the Maundy set. The whole collection of 9 coins, plus the 4 coin Maundy Set comes in a large blue deluxe presentation case with an illustrated booklet/certificate. Very limited availability.
One of the most interesting coins of the Decimal series is the 10 Pence pieces, especially the old large-sized coins. The first Decimal 10p was introduced in 1968, replacing the two shilling coin in preparation for decimalisation in 1971. It features the portrait of Queen Elizabeth II by Arnold Machin on the obverse. Today you get the small-sized 10 Pence in your change, as this large-sized coin has not been made for over 16 years.
