Application of the extended fuzzy pointing set to coin grading

The application of the extended fuzzy pointing set to coin grading is described and illustrated by examples. The coin grading example considered takes advantage of the fact that the extended fuzzy pointing set S_n has been equipped with special operators with certain induced properties. In addition, the fact that the valuation space is endowed with a lattice structure is exploited. It is believed that coin grading is a paradigm for more important applications. For example, the technique considered here could be used in grading semiconductor wafers before implantation or for the interpretation of data transmitted over noisy or damaged channels such as in space communications
