Yes, looks like a '41 S Large S. Roughly speaking, the Large S variety are worth up to 10x the Small S variety. You look through a lot of nickels, so it may be worth your while to put together a roll of Large S nickels. Here on the East Coast, it's taking me a while to put one together...largely because I haven't CRHed in a very long time now. Putting a roll together juxtaposed to the rolls of Small S variety you will put together will give you an idea of the level of difficulty/scarcity in your part of the country. I suspect that you'll have an easier go of it relative to my own.
