Another excellent post commems.

I would value and appreciate a single post that focuses on each of these tremendous medals from you set ... complete with the insights and history of the issues for which we have come to respect and enjoy from your wonderful collection.
Pleased to share that I have in my collection an example of the 1915 Pan-Pacific medal. Mine is a chocolate brown example that has some wear ... perhaps AU55.
I've never imaged the medal ... so no photo ... perhaps I will do so ... but it's the same as your lovely MS64 example with some circulation rub.
I am intrigued by the incuse impression on the obverse rim at 5am ...
AITKEN FECIT ... a medal designed by classic commemorative legend Robert Aitken.

Perhaps you can tell us more about this one in a separate post?
Enjoying and learning from everything you share with us.
