I yesterday I bought big coin lot with different coins. In this lot I found this one:

I check it and I understand that this is old Saudi Arabia coin:
1 Qirsh - Abd al-Azīz Hejaz and Nejd - 1926
When I check in ebay I was surprised how much does it cost.
Do you have story of this coin. Why his price is so big? Small mintage or something interest story behind?
If you know something please share with us!
