Good day people...

Please to advise the worth of these notes.

Most of these notes have average values at which collectors on numista bought them, that can already give you an idea:
https://en.numista.com/catalogue/index.php?e=arabie_saoudite&r=&ct=banknote&im1=&im2=&tbb=y&tbc=y&tbl=y&tbt=y&tbf=y&cat=y&ru=&ca=931&no=&v=&i=&b=&ib=&u=&a=&dg=&m=&f=&t=&t2=&mt=&g=&se=&d=&c=&wi=&sw=

You can also look at the sold items on ebay to get some extra information. Beware that grade is important, some of your notes are very nice while others have seen a lot of use.

And if you want to swap on numista, I suggest you add your notes and doubles in the database.
