Some collectors make a serious -- and frustrating -- mistake with Silver Dollars: comparing one mint to another, expecting all coins to look the same Doesn't work that way, folks!
Remember, most coins were minted for circulation, not collecting. The finished product was affected by die condition and preparation; planchet quality; press settings; and even weather conditions. Here are some brief details about the "make" of Morgan Dollars minted between 1878 and 1904.
