<p>[QUOTE="Bob Evancho, post: 7420200, member: 84595"]Counterfeit. For those who are able, do a forensic diagnostic analysis of the die characteristics of a genuine 1873 Trade Dollar (circulation strike or Proof). I don't have the coin in hand but if I did, When I am asked by authorities to determine if a particular coin is genuine or counterfeit I use many methods. Is it silver and the correct composition (use XRF analysis)? Is the weight correct within tolerance (use precision scale reading hundredths or thousandths)? Is the diameter correct (use digital electronic caliper)? Now is it comparable to know genuine die characteristics? The OP's coin is NOT. All know dies have the arrow point between the 2 and 0. Is the lettering font correct for all known genuine dies? I won't go further because we don't want counterfeiters to know what we look for to determine their errors. They are getting better but still not perfect. There are many counterfeit experts on CoinTalk and we can all learn from their observations and the techniques they use to determine authenticity. But remember nobody is perfect. Ask PCGS about the micro o silver dollars of 1896, 1900 or 1902. Buy the book before you buy the coin. There are good books about counterfeit detection. Read at least one to become familiar and enjoy the coin collecting hobby.[/QUOTE]</p><p><br /></p>
