I am summoned...

The note in your third post is from China; the Central Bank was the main government-backed bank of the Republic (Nationalists). The
Customs Gold Unit was a currency unit released by the Bank to attempt to combat worsening inflation; there were 20 "old yuan" to a CGU. The Republic was losing the war, and confidence that they could turn things around and start winning was low. The attempt to curb inflation failed; notes as high as 250,000 CGU can be obtained fairly easily, though you probably won't find notes above 25,000 CGU in a bargain bin.
This note is dated Year 19 of the Republic (1930), but notes with this date were issued up until the end of WWII.
