It sounds like an error in the coin stamping process. When coins are minted, a round, blank piece of metal is punched out of a strip of flat metal. The flat planchet (the minting term for a blank coin) is then moved along until it is between two steel dies that have the coin's reverse images engraved on it, one side of the die is pressed downward onto the planchet as it rests on the opposite die. Sometimes these dies will come unbolted and rotate or become misaligned and produce a coin with a crooked or off-center image. Coin collectors love these "error" or mint fault coins. It is certainly worth something to the right coin collector. I would put it on eBay and see what happens.
Yes, an AGN is a compact region at the center of a galaxy that has a much higher than normal luminosity, over at least some portion, and possibly all, of the electromagnetic spectrum.
There are at least 2 ways that can happen: First, if two blanks accidentally landed in the coin press at the same time, the press would only be able to strike an image on one side of each. The extra thickness of the double blank would also cause the images that did take to be much sharper than normal. Also, the coin would be the same thickness and weight as any other silver dime. This error is fairly uncommon and you'd need to have it evaluated by a dealer who handles error coins. On the other hand, if the coin is thinner and lighter than normal, someone used a file or other means to smooth off the back side. In this case it's a damaged coin worth only its silver metal value, maybe a dollar or so.

Smooth vs. Rough surfaces. Rough surfaces have more surface area than smooth surfaces. This means that there are increased incidences of molecular reactions between the surface and object
Yes, because of the bleeding you should push the obgyn to see her sooner, nausea and fatigue are normal, if he/she cannot see her sooner, at least take her to an urgent care center to have a pelvic examination

You have an error called an off-center strike. That happens when a coin blank doesn't land squarely in the collar that holds it when the coin press strikes the image on it. Unfortunately a minor offset isn't worth very much on a penny. You'd need to have a coin with at least 15-20% of the image missing to have any significant extra value, and even then it would only be a few dollars.
