1939 Palestine 1 Pound Note

I bought this note from the British Mandate of Palestine. The Palestine Currency Board produced banknotes with values of 500 mils, 1 pound, 5 pounds, 10 pounds, 50 pounds and 100 pounds. It’s my first piece of Palestine currency; I’m working on a complete date set of the coinage.

Egypt Bond, or Receipt, for Palestine War

I believe this is an Egyptian bond from the 1940s, or donation receipt, for people to support the war in Palestine. I bought this one off eBay. The note’s denomination is 10 pounds.

I’m interested in learning if these notes were bonds that got paid back or if they were donation receipts. I’ve read descriptions online stating both.

The bonds come in denominations of 50 Pounds, 10 Pounds, 5 Pounds, 100 Piasters, and 50 Piasters.
