This is a Historic Edition for The Royal Mint and British and Northern Irelands coinage. It is the first year they at the RM started producing Decimal Coinage. These Proofs are encased with a pristine hard plastic case which is in excellent shape as it has been well protected in it`s orig. cardboard folder which is also Pristine.    The orig. RM envelope shows some wear.   The coins are somewhat toned , copper more-so than clad but actually makes them more enjoyable to look at.   The denoms.  are - 1/2 new penny , 1 new penny , 2 New Pence and 5 ,10,and 50 New Pence.   Total of all 6 coins and a RM copper medallion as well.    A Truly Gorgeous set !
