Ok, so apparently this been around since its discovery since 1961 . Please read about this fascinating story . SilverTowne Now in Possession of a Very Rare Wartime Nickel
Here is something I posted here on CoinTalk on June 15th 2015.. This does remind me of a story I read not to long ago. Interesting read! The Frith Nickel! I want to share this webpage with you - http://www.coin-collecting-guide-for-beginners.com/rare-nickel.html
Here is that thread.. https://www.cointalk.com/threads/nickel-with-two-mintmarks.265055/ A case of Pareidolia and NWT Newbie Wishful Thinking
For those that might be unclear about the large S variety. Most 41S Jefferson Nickels were struck with a small S. I was going to break down the variety for ya, but @Lehigh96 did a thread on this variety that I think is a must if you like Jefferson nickels. https://www.cointalk.com/threads/variety-1941-s-large-s-jefferson-nickel-fs-501.213511/ It seems that since 2012 more dies have been found with the large S. Variety Vista has 16 dies available for viewing, including a few RPM's http://varietyvista.com/04a JN DD Vol 1/DDR Detail Pages/1941SMMS00201.htm
