it at face value.

Unless it's a rag you got on the cheap and feel like experimenting!

Experimenting? Heh. Just stay away from the bleach and the ironing
board, please.


One of the challenges in running a foreign exchange business is
keeping track of which countries' notes are still valid and which have
expired.

Do you run such a business?

Yup. It is one part of our operations. The bulk is in coins and
bullion with an FX department and we sell/custom-make fine jewellery.


If so, how do you keep track?

What the other poster answered with. The MRI guides and updates is
what we use.


How many "old" notes come through such a business? Examples?

Notes from older European countries, the Middle East, Asia. We even
get some old Jamacian and (mostly fake) US Colonial script. Regret I
don't personally work in that department so my knowledge is limited.

FWIW.
