The Egyptian Government was in real need for silver coins on 1937 AD and since the state treasury held old soft worn silver coins not suitable for exchange at a total value of 600000 Egyptians pounds a decision was taken to melt said coins and to re-mint them in The Royal Mint in London 

The old silver coins were melted and re-minted with the following denominations 

25000 coins of twenty piastres each with a total value of 5000 pounds

2800000 coins of ten piastres each with a total value of 280000 pounds

4400000 coins of five piastres each with a total value 220000 pounds

500000 coins of two piastres each with a total value of 10000 pounds

All pieces are bearing King Farouk's portrait and mint year 1937 AD

Due to the weight difference between the old soft worn coins and the new coins total value for later reached 515000 Egyptian pounds only
