Suspicious arabic ? on 100 dollar bill

Received some $ in cashing a check at a local bank last week with these stamps on the reverse.

The 'R' seems fairly benign, but the arabic symbol causes one to pause.

Any ideas / other sightings of the like? (I've had arabic appear on another c-note awhile back, but never investigated it) Might just be a stamp of a local money exchange or something... anyone?

Dunno. I'm curious to know what the stamp means and where it came from.

Probably just a secretary testing her stamp on what she had handy before stamping a document while the money passed through an Arabic business or bank.

I never had sightings of the like on my money other than scribbled math calculations. I've read that most money in circulation are stained with coc aine.

That certainly doesn't surprise me. I wonder what the actual number is though of bills stained with coc aine.
