Sweating In the process of sweating, coins were placed in a bag and shaken. The bits of metal that had worn off the coins were recovered from the bottom of the bag.Sweating tended to wear the coin in a more natural way than clipping, and so was harder to detect.

The Saudi Arabia Gold One Guinea Coins were only minted in 1950 and 1957, I think your coin is a modern reproduction of the coin and could still be 22-carat gold a bit like the jeweler's copies of sovereigns from the middle east some times with 22 stamped on them. The reason I think this is your coin looks to weakly struck and very soft detail with no obvious signs of wear. I hope you get to the bottom of the mystery and look forward to what you find out
