1923 Buffalo Nickel Error Coin

Hey guys, just joined the forum. Wanted to post up one of my Buffalo nickels w/errors. Pictures are kind of blurred (and I apologize about that) because I took them with the coin still in its' plastic holder, but I zoomed in on the errors so you can at least get the gist of how I am explaining them. How would you classify these errors? 1923 Buffalo w/out Mint Mark. Front appears struck a second time just inward of the outer ring which goes through the word Liberty as well as right past it, and there is also a line going through the Indian's eyebrow which looks to be apart of that same error? Also, it looks like there is a spear going into the Buffalo on the back (not literally, just material that does not belong there), which can be seen "under" the E and Pluribus sticking out of its' back...
