Two collections from silver coins of 5.1 and 20 piastres were presented to king Farouk to select from them one set for circulation

The two set were identical in obverse and reverse but have different edge reeding designs

The first set has a reeded edge same as King Fuad coins ( fig.1)

The second set has a reeded edge with small beads in the middle . ( fig2 ) new design

King Farouk selected the new edge ( fig2) for his silver coins because and elegance and since it was hard to counterfeit or fake

While the first set with the classic edge reeding ( fig1) were kept by the King in his private collection and they are very rare
