Hi,
I got this 1 paisa coin in a swap as a 2031, which is correct, but the Nepalese number indicated in numista, does NOT show the alternate way of writing the ONE, which you find in the SCWC as a straight NINE.

in numista, it's written like this:

In the end it's a general question question about the numbers from Nepal, since you also have alternates on the 5 and 9, if I remember correctly?
How to show alternate numbers with the same “content” is certainly not an easy doing!
