My 'set' only mostly complete at this stage.
I will post a list. Some coins were struck with the same general type over a period more than one century, but a few gold coins included in the list.
Will take a day or two to write up a list of selected coins, out of a collection of about 1,500, mostly less than 300 years old.

It has taken me nearly 40 years to build this 'set' so far.
One of the rationales for collecting in this way is
that if one collects a specific set (say, a date set of Lincoln pennies), the only coins of significance are the key coins.
With my 'set', each coin can stand on it's own, and is significant in it's own right.
By collecting across the whole of numismatics, I can also cherry pick across the whole of numismatics, looking for best value for money for each purchase. Such an approach requires a lot of research before making a decision to buy each item.
I also get to make a study of World history over my lifetime, - the first step to becoming a 'culture vulture' !
