I was sitting in prison (my job, lol) last night with my loupe and a pocket load of change and came across these coins that struck a little interest....
This first one reminded my of the 1994 with the double columns. I took two pics with different lighting.


This second has what I'm guessing is a die crack going from the edge of the rim to towards the center on both sides of the coin, but not in the same place.


And finally this nickel. Is there any doubling in the date, or am I trying to see something that's not there?

THanks for your help!
