5 Kori - Victoria [Khengarji III] - Princely state of Kutch – Numista that one listed as minted between 1938-1943, and that is correct, but those years are AS not AD. And that breaks a time-based filter for someone who is looking for coins of a specific period. I am not sure whether that is an issue with coin definition itself or with numista not being able to specify year format.
Actually, I am getting more certain that it is a coin definition that needs to be changed - since coins have AD year on reverse, I suggest changing the listed year to the year from reverse and use the year from the year fields as a comment. See 5 Kori - George VI [Khengarji III] - Princely state of Kutch – Numista for example.
