Hello. When I searched these bills it brings up a few examples & I do not know which of the examples they actually are. Curious if they hold value? 2 are in excellent condition.
The Tanzania note (if it was in uncirculated condition) can be had on eBay right now for around £6. But yours has a corner fold so it is not UNC, it will fetch less.
The Yugoslavia 10 Dinara note from the 1960s is very common, it is on ebay now for 99p uncirculated. It is one of those notes that you find in a batch of 100 world notes if bought off ebay or Amazon.
