I am looking to trade mixed random year circulated US Silver Dollars for an excellent or better 5 1/2" Super Blackhawk or Bisley .44 magnum or .45 in stainless Steel. I value my silver dollars at $28 each shipped. I'm looking at a maximum 20 silver dollars to make this trade. That puts my value total at $560. I do not mind shipping at all for the right deal.
