Just received this coin and I'll be damned if it doesn't look like the 7 was struck over a 6. Can't find anything online about it either. Cool die crack on obverse too. Would love to know if you think I'm crazy.
I can't tell. It looks a little like a 7/6 more in the first photo. I got this recently metal detecting:
Here's some interesting info I found on the world of coins.au website regarding this coin http://www.worldofcoins.eu/forum/index.php?topic=22779.0 Capt A. L. C. McCormick, the Bombay mint master and the designer of the 1 anna, was not happy with the 1906 1 anna, as after the polishing process much of the detailed design on the King’s head was lost. It is possible that these 1906 experimental coins may have been melted, although no documentation of this has been found so far. McCormick asked the Royal Mint in Britain to produce new dies that would improve the king’s head and edges of the coin. The dies and tools were sent in September 1907 and arrived at the Bombay mint. However none of the tools were used as the Bombay mint had produced an improved die and used it for producing the 1907 Anna. The Bombay mint was the only mint that produced the Edward 1 Anna coin. This could possibly explain how a 1906 Anna with a host of die cracks came to become a 1907 Anna. Check the edges of the op coin...they are curious.
If there was a 1907 over 06 (and there very well could be). It should be a known variety and listed in a world coin book, or online somewhere. I like the coin very much. I am not sure about the "crud" behind the 7 that was not removed from acetone. Find the strongest magnification you can (loupe/microscope) and examine the coin under a very bright light. If there is a 6 under there, you will be able to see it. GL!
I showed the coin to my wife (who doesn't care about coins) and she said she sees a 6 behind the 7. I guess my next question is in regard to authenticating officially. How might one go about verifying the existence of a new variety of a coin. I wouldn't make a fuss about it, but because of the rarity of the 1906 version, this could be a significant find...or I could be seeing things.
So, we now have some clarity and closure on the issue. At the urging of @GDJMSP I soaked then gently used a toothpick to work on the crud around the 7. Alas, it's gone as is the impression of a 6. Not the outcome I was hoping for but at least it's an outcome. And as the saying goes, if it seems too good to be true...well, you know the rest. Still a cool coin in pretty nice shape. Thanks for the input everyone.
