But why did they produce such a coin not so long age? I do not live in the UK but I never saw or heard about it
It is very special and beautiful
None of these are from the UK, don't be fooled by the Queen, she appears in lots of different places
The Bermuda coin I believe was not meant for general usage, just a commemmorative coin. However, the UK themselves have 7-sided coins like the Falklands coin - both their 20 pence and 50 pence coins are 7-sided to this day, and have been ever since they were introduced in 1969.
