I recently came into a collection of bank notes from various places and points in history. Among them was a small collection of Japanese Occupation era Philippine Bank Notes (Pesos, Centavos, etc.) which has lead me to start to investigate more into that time period and more about the places Japan occupied during the war. [1][2] I have other banknotes from similar tumultuous times (Korean Yen, before and after revolution Russian and Soviet banknotes, same for Iran). I find it interesting that it seems one of the first things new governments do is find engravers, make high-quality engravings, and start printing new currency. 1 - https://en.wikipedia.org/wiki/Japanese_government-issued_Philippine_peso https://en.wikipedia.org/wiki/Japanese_government-issued_Phi... 2 - https://en.wikipedia.org/wiki/Japanese_invasion_money https://en.wikipedia.org/wiki/Japanese_invasion_money
