I bought a silver dollar from a Tibet Antique Chenbb dealer that has trade dollares and 1886,1887 ,1888,1989 cc silver dollars'  bought a 1885cc morgan dollar with shipping about 80.00  1st problem it weighed only 12.5 grams. I could see were the rim had been rolled on th the coin. It had a off color to it. To top it off the carson city mint did not release 1885cc silver dollars. The trade dollar 1878 weighed over 28 grams and looked like the rim had been added to the coin. the rim lines aroung the rim were not straight and smadhed in at different areas. I have sent back silver dollars,trade dollars , and philipino dollars to several merchants stilled sellling on ebay. I am working on the one that sold me the 1885 cc silver Morgan now. These people should not be allowed to keep selling on ebay. Be aware of the jade jewelry also, its cheap plastic fakes. You can get the same stuff in the 25c gum ball machines.
