In the article
https://en.numista.com/catalogue/pieces1300.html
there is a mess in mintage section.
1. Instead of
1930 8,888,000 Calcutta
1930 • Proof, Calcutta
there should be something like
1930 8,888,000 Calcutta
1930 Proof, Calcutta
1930 • Bombay
2. If Numista catalog is ready to describe proofs separately, then why there are no proofs for all other years and 1930 only is possibly described?
