Analysis of information sources in references of the Wikipedia article "Mark McMenamin" in English language version.
The putative Carthaginian coins must now be removed from the body admissible evidence favoring a pre-Columbian transatlantic crossing. It gives me some chagrin to admit this, as I had earlier come out mildly in support of the authenticity of these coins (McMenamin 1999b, 2000a, 2000b). Weak evidence (involving measurements of die axis; the Arkansas coin has a die axis [33 degrees] differing from the Alabama type coins [12 to 20 degrees]) in support of the authenticity of these coins (McMenamin 2000b) is superseeded by the strong evidence in the current work.
