I tried this yesterday and must have done something wrong. Can someone tell me about this currency?

I wish I could help, but I don't know enough about World Coins let alone World Currency

It's a Tunisia 20 Francs note issued in 1943.

From the wiki for the Tunisian Franc:
In 1903, the Banque de l'Algérie introduced 5 franc notes with the overprint "Tunisie". These were followed by 500 francs in 1904, 20, 50 and 10 francs in 1908 and 1000 franc notes in 1918. Between 1918 and 1921, the "Regence de Tunis" issued notes for 50 centimes, 1 and 2 francs. The bank introduced 5000 franc notes in 1942, whilst the "Direction des Finance" issued 50 centime, 1 and 2 franc notes in 1943. The last 5 franc notes were issued in 1944.
In 1946, the name of the bank changed to the Banque de l'Algérie et de la Tunisie. Notes were issued for Tunisia in denominations of 20, 50, 100, 500, 1000 and 5000 francs, with the 20, 50 and 100 franc notes being replaced by coins in 1950.

No idea of the value but your seems to be in pretty good shape. Here are a few currently up for bid on ebay ...

Dan thanks for the site and thanks Marc for the info. I have two more with a 1941 date on them, one in great shape the other one not as good. The 1943 is in great shape. I know nothing about selling on Ebay. I would like to get rid of all the world currency I have. I have a lot of Canadian coins and some dollar currency. Thanks again both of you. I am going to post some more currency and then try some pictures of coins.

Happy to help. Don't know very much about notes but love searching and learning. I also don't sell anything really and have not sold muh on eBay but Daniel could probably help you there as well as he sells lots of coins on ebay. Look forward to seeing more of you coins and notes.
