In the first picture, can you read any of the letters? It looks like "TES". THe "E" would be at the top of the coin whether it is a shield or a V. Unless you can get a little more detail it will be hard to ID it precisely. In either case it would date from 1866-1913.
Looks like a V nickel to me. Unfortunately often they don't come out with very much detail. I have tried first rubbing around with a toothpick to bring out more detail.
If you dig V nickles and Indian Head pennies in the desert most of them come up like the 2 that I posted. When I dig them out of fertile ground most of them are toasted. If you clean them too much the ones that I've found turn an ugly pinkish to brownish color, uglier than when they came out IMO.
