Without a first-hand inspection, it's impossible to tell what you have. It could be an impossibly rare mint error, or a coin altered after it left the mint.
I suggest you check out the show list on http://www.anacs.com to see if the ANACS service will be in your area in the near future. If so, you can take your coin to the show and get a free professional appraisal from them.
If not, check out http://www.coinshows.com to see if there are any shows in your area, where you could get a first-hand appraisal from a dealer.
Good luck,
Dan
The reversed lettering could indicate that you could have what's called a brockage error. Brockages occur when a coin fails to leave the press and stays in while the next blank is fed in. The first coin then acts like a die, except that it already has positive images on it so they're pressed backwards onto the second coin. Brockage errors can be moderately valuable. For example Jefferson nickel brockages are quoted at roughly $50 retail by MintErrorNews.
However there are also fake brockage errors made by manually hammering a one coin onto another so I'd definitely second Dan's advice to get an in-person appraisal.
CD = Cross direction MD = Machine direction
The shadow faces the opposite direction from where the light is coing from.
looking backwards
looking backwards
Backwards K's are for a strikeout looking (not swinging the bat).
So everyone would start looking for his body in the opposite direction than the way he was going.
Because of the definition of addition and subtraction. When looking at a real number line: when you add you move to the left or up, when you add the opposite of a number you move in the opposite direction.
Looking is backwards. A looking strikeout is subjective to the home plate umpire that night. A swinging strikeout is objective. No doubt that he missed on that third strike; that's a K. K=swinging forward. Backwards K=looking backwards at the umpire and being K'ed

The "K" is placed backwards in cases where the batter strikes out looking.
The opposite phrase you're looking for is "the decrease."
you can feel someone's looking at you but you're looking in a different direction because your corner eye (s) could see them looking at you or its instinct
