I'm happy that you enjoyed this post. As you know, the $5 1934A and $10 1934 and 1934A North African notes were Silver Certificates (instead of Federal Reserve Notes). I am not aware of a thread that specifically discusses the North African notes (though they have always been immensely popular with collectors).
The 1934 $10 North Africa notes only come as Mules and the 1934A NAs are all Non-Mules. The 1934 NAs are scarce, and high collector demand has kept prices high.
There have been attempts by the unscrupulous to remove the "A" from series 1934A and pass them off as 1934 series. However, these alterations can be easily detected as genuine 1934 NAs will only come with the following front plate numbers: 116. 122, 123, 125, 126 and 127.
The 1934 NA Stars are significant rarities and the small number of known examples (all circulated) tend to bring strong prices. The 1934A Stars are relatively available, though high grade examples can be pricey.
1934A NA notes also come as a variety: Late finished Face Plates #86. Stars of the lfp #86 are also known but scarce.
The genuine 1934's should have micro face plates, while altered 1934A to 1934 would have macro face plates, as all 1934A's have macro face plates.
