As suggested above the app Coinoscope correctly identified the coin. There's also another app called Maktun that also did well. I used the pictures as displayed above and both apps correctly rotated the images.
Coinoscope is easier to use as it requires only one image. Maktun requires two images so it can better locate a particular coin in a family of coins. I find both occasionally useful. (If I knew less about coins I would find them very useful.)
