Old (Ancient?) Afghan Coins - Help Please

Hello. I am new to this site and this is my first post. I have also posted it in the Identification section.

I hope you can help.

My elderly father in law has lost a box of old, rough-cast Afghan coins in a particularly nasty robbery. Some masked men broke down his front door, restrained him on his back on the floor and ransacked his house.

I am now trying to place a value on these for the loss adjuster. All my father in law can remember is that they were old when he acquired them before he left Kabul in the 1950s. Thankfully, some were left behind and I am posting a photograph. I have other photos if needed.

Any help you can give me in dating and/or valuing these would be much appreciated. He had a box full of them, approximately the size of a large match box.

Thank you. RK
