I'm new to coin collecting so bear with me. This coin has two distinct lines going through it. On the obverse side it starts about ten o'clock, left side, and travels through her forehead then turns south through her ear, then a wide curve, through the "8" and ending at the edge of the coin. On the reverse side of the coin, a thick line starts at the "A" in America, goes left through the eagle's beak, then to the other side of the coin's edge. Neither line coinsides with the other. What have I got? Does it make the coin more valuable? Thanks in advance.
