Getting back to my commemorative type set today. I just added this one recently to the collection. It is the 1915 Panama-Pacific Exposition Commemorative Half Dollar.
From February 20 to December 4, 1915, San Francisco, California, United States, hosted the Panama-Pacific International Exposition. Its claimed objective was to commemorate the Panama Canal's completion.
The legislation for a silver half dollar, a gold dollar, a quarter eagle ($2.50 piece), and two $50 coins—one round and one octagonal—was approved by Congress in January 1915 for commemoration.
Above is reference image from CoinSnap that you can compare to the one from my collection further below.
There was around 200K authorized to be minted, but net distribution was just over 27K after most were melted down. They are 90% silver and weigh 12.5 grams.
Finding this particular commem in this condition for the price I did was very difficult. I pulled it off for half of what I think the numismatic value is. I am placing this at around XF to AU condition. If you want to try it against
