This is the first Royal Mint set featuring coins of the decimal Pound Sterling. The set contains some coins dated 1968 and some dated 1971. Interestingly, the leaflet in it talks about events in 1969 in future tense, i.e. as if they are still to occur. Strangely, it contains no 50p coin even though the first of these were issued in 1969.
The coins are in Brilliant Uncirculated grade.
