Different colors on 50 centimes banknote 1944, Algeria
I have a 50 centimes banknote 1944, Algeria.
It is #97a with serial number C2 # 369992
On the front it has a nice red color, but the other side is yellow.
What do you think, is that something unusual or just regular stuff? It doesn't seems as like paint that has lost its tint or faded in the sun. In any catalogues I had a look, it is always the same colors on one banknote.
Many thanks for your opinion
