1000 Afghanis 1939 Zahir Shah

An expensive note that isn't often seen. Thanks for showing us.
As far as price and condition this is impossible to tell based on the one photo. We do not know what the back looks like. The front shows evidence of handling marks, edge bites, a strong center crease, and creases on the end, from being folded into thirds.
Judging from these things only, the condition would be:

IBNS - VF or Very Fine
PMG - VF or Very Fine Grade 20 or 25
Legacy - VF or Very Fine 20 to 30

Looks like these don't come up that often in the auction markets.
One sold with Heritage auctions in 2014 graded by PCGS (Now Legacy) in grade 50 Almost New for $2115.00
I found none sold on ebay through their search.
If you are aware of other condition issues or the condition of the back, you can make the correlation of a possible price from that sale.
Best of luck!

I believe it is 1939 P27A as it appears to be first portrait but there is no image in my SWPMC. BV for VF =$500 so pretty tough note to come by.

It also looks as if the note has been darkened by either oil or some other source of soiling (primarily throughout most of the right side of the banknote). Difficult to tell from photo. There also appears to be more than the one hard vertical fold down the centre (& issues along the right & top right borders). I believe it would grade F15 to VF20 (at best) but not EPQ (nor original due to paper soiling).
