I have a bunch of slabbed mid grade $60-$100 Morgan Dollars for trade. If you are looking for a particular year and grade desired, let me know. I collect proof issues, anything pre 1900. I might be interested in an ancient.
I also have some higher end coins I might be willing to discuss trading. I have some higher end seated quarters, Buffalo nickels and silver trimes that I have duplicates of.
I am of firm belief of the honor system as well. I don’t think NGC would want to monitor or govern such a system, though.
