If by turning the coin left to right and the reverse is upside down on each turn, this is the way it should be. The 1989 Congress bicentennial Half Dollar was struck as Proof (S) and Uncirculated (D) and both have the same retail value of $9.00
No such thing as a "strike mark" but U.S. coins do have Mintmarks. For Morgan dollars, they are on the reverse just above the DO in DOLLAR.

Offset in geological features: Fault offset can be recognized by observing differences in the alignment of rock layers, faults, or fractures on either side of the fault line. Topographic expression: Fault offset can also be detected through differences in elevation or alignment of landforms on either side of the fault. Displacement of man-made structures: Buildings, roads, or fences that are offset or displaced along a fault line can also serve as indicators of fault offset.

The U.S. did not strike any silver dollars with that date. The only dollar-type coins issued that year were Trade Dollars. See http://www.numismedia.com/fmv/prices/trddlr/pricesgd.shtml for a price guide. If your coin does not have the words "Trade Dollar" on the reverse I'm afraid that it is a fantasy piece or possibly an outright counterfeit.
no it is a strike slip fault i had also had confusion on that.
Neither. It is a strike-slip fault.
