Try this first on some silver article of lesser value than the Morgan,such as a silver spoon, etc. 1. In a glass or stainless steel container make a hot solution of sodium carbonate [washing soda]about 5 %- it doesnt need to be boiling, just hot. In this place the silver article and piece of aluminum metal, a piece of a sheet or a nail. The aluminum and the aluminum MUST be in close physical contact. After a few minutes remove the silver, rinse, and examine. 2. Query a silversmith or dealer in fine silverware, or a coin dealer [not the one you want to sell the coin to]. 3. Try a commercial silver cleaner or tarnish remover [with no abrasive], such as TARNEX. Regards from C. A. Crutchfield
