Can someone explain what's going on with this page? I have a 1946 ½ Rupee with a clear dot/diamond mark, but this page doesn't show that as existing despite my Standard Catalog of World Coins contradicting that. It seems that most people who have this coin have added it under the ND (No Date) entry, which seems odd. There's also this “Houghton Monogram” mark which I cannot find any information about anywhere and my coin certainly doesn't have it. Does this page need to be updated to remove that entry and make it a standard “1946 •”?
Thank you in advance!
