Hi Dr. Saha, I have very little knowledge of Indian coins however I've purchased all grades of "struck for circulation" British. I found the following pix With the above caveats I don't know about your coin. There are several diagnostics. I am a little concerned about the diebreak on the obverse of your specimen. While common on coins of my speciality (Latin America from the 1830's), I think by 1911 the British had much better quality control. Thus I'd be surprised to see this sort of raised damage on the dies of a British Imperial coin. The standard weight is listed as 11.66 gm so your piece is within spec. I don't know the accuracy of your scale. For .01 gm, you really need a laboratory balance with calibration weights. Your picture could use some improvement but the details on the King's robes and the details near the coins edge obverse appear indistinct which is worrisome. Maybe you could write to "thecoinsof india" the source of the pix I posted and ask them? They appear to be experts in the field. These appear to be really neat coins from a historical viewpoint and I wish I could visit that part of the world where I could find one. I can understand why you'd want a 1911 1-rupee as most of them were withdrawn and melted due to popular rejection of the "Pig Elephant".
I'm slowly working on a complete Aussie penny collection. Here's what I have so far. 1962 Double Die, fairly common, look at her nose, hair ribbon and around the II. A fairly nice 1935 with almost all the crown pearls My 1942 Reverse that I am fond of, Looks a lot better in hand. And than the rest of my collection. Trying to find an album to put them all in, but they're super expensive!
I will dig mine out, measure it and get back to you on that. In the meantime a very effective way to check for silver is to do the ice cube test. Hold the edges and push an ice cube into one side the whole coins should be almost instantly cold. Pair that with the right size and weight and that's good enough for me !
not a halfcrown,if it is a crown it is coin of value,most likely a florin but not 1847,i cant see the date ,can you give us the diameter and weight and check the date in roman numerals on the reverse.still a very nice collectable coin
BRITISH COIN, Young Victoria (1837-1901), 'Gothic Crown,' 1847, edge undecimo (ESC 288; S 3883). Virtually mint state and attractively toned.
two crowns i have not the best quality i am afraid. The 1821 has a counter stamp of MB which i am not able to interpret.
I have seen this counter stamp before on a different coin. I know it had to be on Cointalk. There a counter stamp thread on cointalk. .
Me too, I saw on a few shillings on eBay Here's my last coin for this month and one reserved for next month. Unfortunately this is another case of some un-sightly scratches on the bust. It really bugs me because it's XF/AU other than that !! This one is reserved for me It's the only one I've seen. Unlike the 1/2 penny (below) which I've seen atleast 10 of I have 3 !
