It is dated 1925, and would have likely been in circulation during the time of WWII. Meaning it piercing the coin is just a random probability. The bullet is consistent with period (copper jacketed lead bullet) with the rifling marks consistent with being fired.It almost looks to me like it is about a 7.62 caliber round (but this is just my best guess). It would make a great collectible! I will include a small plastic display case with it (it isnt much, but is a great way to display it and protect it). The bullet seems to be wedged in there pretty good, so I believe it is secure. The coin has been authenticated as well. This would be a great addition to any collection, a great conversation piece, a great teaching tool, or perfect for a gift!
