Thanks Jim,
Just read last week that the Chinese are cutting US Morgan dollar in half (lengthwise) then gluing different mint mark reverses onto other obverses to get "rare" mint mark coins. They are encased in counterfeit graded slabs, including the hologram seals and are real good assembled coins. Somehow the coins match up with the grading service reports, so these are the ultimate buyer beware. You have to know who you are dealing with these days.
