India-Portuguese 1918 GOA 1/8 Rupia, Oitavo

Hello,

NGC shows image of reverse to be

 yet I came across image of coin claiming to be KM#309 that has different reverse:

 Can anyone explain why there is a difference?

Thank you...   Dan

 I only know French language, and Huit is 8 and Quatre is 4, so maybe similar in Portuguese; then ...
I guess Oitavo means 1/8
and so Quarto means 1/4

So they are different coins - if NGC show the Oitavo as 1/8 then that is correct (if I am).  

P.S. Apart from that, this page below says the 1/8 is only 1881 so not sure where 1918 comes in.

The 1/4 below is KM# 310 and only 1881 or rarely 1885 - so also not 1918 year.

 So the second image you show is most likely 1881 date and 1/4 Rupia and KM# 310.  

Thank you,

The '1918' was a typo, meant to be 1881. Your explanation is correct. The coin listed with the 'Quarto' on reverse was pulled from auction as having been listed incorrectly.

Again Thank you...     Dan

Verweis : ZacUKI only know French language, and Huit is 8 and Quatre is 4, so maybe similar in Portuguese; then ...

Dan is correct and so is our catalogue.

In Portuguese, Oitavo is 1/8 and Quarto is 1/4.  Zac is absolutely right.

This one is in my collection. Any opinions of grade and/or condition are always welcome. Thank you...   Dan.
