Hi Andyj, The cardboard coins that you have come from a box of school teaching coins. The box would have contained between 100 to 200 coins for use in the class room. Longmans is an Englih company who specilised in the retailing of cardboard school teaching coins.The coins were manufactured in Germany as at that time it was illegal in England to reproduce the legal currency. I also have some of these 1911 and 1919 Indian coins in my cardboard collection. I also collect early Toy coins.
