Hi Joyce. Welcome to the forum. I'm going to stick my neck out, and value your coin at somewhere between the ~65¢ bullion value of its silver content, and $2. (The more "well circulated" the closer to the bullion value .) A more exact estimate would require seeing a clear picture of both sides. It's one of 11,392,000 19mm wide, 5.6552g, .500 silver shillings minted in Great Britain that year, and is listed in the Standard Catalog of World Coins as KM#853. My guess is that your assumption that it is an Indian shilling is based on the reverse legend "IND*IMP" in the upper right quadrant, and the apparent lack of any other country name. If I'm right The obverse has a bust of King George VI, facing left, with the legend "GEORGIVS VI D:G:BR:OMN:REX", and The reverse has the English crest showing a lion facing left atop a crown, with "19" to the left and "41" to the right, and the additional legends "FID * DEF" in the upper left quadrant, and "ONE SHILLING" across the bottom. The obverse legends translate as "George VI by the grace of God King of all the Brittains"; and the reverse translates as "Defender of the Faith, Emperor of India, One Shilling." How did I do?
Roy,you are correct.You have got a very good knowledge about a lot of numismatic-related areas.I am amazed that you have shown a lot of interest in British coins. Aidan.
