I cant find mintage numbers for the dot variety of this quarter anna. Not in my world catalog, or numista. Anyone know? I'm guessing that these were struck during the time right after Edward abdicated the throne, and there are plenty of these without dots. How can I find out?
This is probably info you already have, and it doesn't break down 1936 by dot vs. no dot. https://www.ngccoin.com/price-guide...na-km-512-1912-1936-cuid-1132947-duid-1476889
My Krause catalog does not mention any variety on this issue, just that it's a restrike and lists the mints, Calcutta & Bombay. Many times small variations are thrown into total mintages unless they are major. The dot may be the factor of which mint but other than that I'm at a loss.
There were none made dated 1937, and the earliest George VI coinage is dated 1938. It could be that there were no dies ready for India with George VI on them, so coins continued to be made in 1937 with George V's portrait, with the dot added below the date indicating 1937.
The dot below the date, 1936, probably has the same historically significance as the Canadian 25 cent coin. George V died in January 1936. His brother Edward VIII unexpectedly abdicated in favor of his brother George VI in December 1936. There was a scramble to produce George VI 1937 coins. The dot below the 1936 coin in Canada is rather valuable. I do not know if your coin is accorded the same significance though. My guess is that the coin was actually minted in late 1936 or early 1937. I would hold on to it and do more research.
Dots on Indian coins are mintmarks. I believe it's for the Bombay mint. It's just a coincidence that yours is the year that the kings changed. There are dots on many different years' coins.
