I had an 1896 penny I found in the school grounds, it was worth about 20c, 20 years ago. Old money isn't really worth much unless it's a defective print, rare coinage.
Do you hear the voices, too?
I have collected paper money for the last 40 years,
I also collect ZAR coins,
What I can tell you, is that most people think the old notes are worth hundreds if not thousands, but in most cases, an old R50 is worth R100 to a collector if in a good condition. It is only the rare notes that are in good mint that are worth something incredible,
I have 16 R50 notes, the red ones in my collection, My favourites are the old Jan VR 5 and 10 Pound notes... once again folk think they are worth hundreds and thousands, I paid R300 - R350 for mine.....
I also have bundles of R2 .... only worth R2 notes...
