The 1st and 3rd coins look fine to me. The 2nd and 4th look like they have been pretty harshly cleaned. I cannot comment on the thicknesses, although the one on the right looks like the edge has been worn more than the one on the left.
A good way to test authenticity would be to weigh them if you have a scale. If you don't, I would suggest getting one with 0.01 precision.
they look okay as to authentication, but 2nd & 4th coins have been quite harshly cleaned. Give them a magnet test and weight them to be sure, the Chinese are getting VERY good with producing quality fakes these days, if you are unsure.

Have a closer look at the thinner of the coins. See how the rim is chamfered outside the reeding? I'll bet once that is factored in (as well as the accompanying optical illusion), the thicknesses will be closer.
actually, jerking the magnet up could give a false sense of it being magnetic. Silver falls into a class of metals that are diamagnetic. If you move a magnet across silver quickly, it will induce a magnetic field in the silver coin and make it move as if it was magnetic (partially). Will it stick to the magnet permanently like iron will, no, but it will definitely move with a strong magnet like the one you describe.
tissue test (to determine if the outer layer is silver, i.e., that it's at least silver plated): 1 ply tissue over the coins, they should appear blast white through it.
Ice cube test (since silver has the best thermal conductivity of any metal): place an ice cube on a coin and on another surface. If they're actually silver, the ice will melt a lot quicker.
Ring test: if you have other silver coins around, strike the edge of one with a dime and listen to the sound. Do the same to the others, they should all ring like a bell.
Other than that, weighing and magnets are nice. However, I believe they look real. What are your concerns with them? (Since you must have some...thus this thread)
Groszy thanks for the possible tests! No concerns, just never held one in my hard and they looked a bit weird, I weighed them and looked at some stock pics. I dont know why I thought they werent real.
