OK. My problem is solved. The weight is 12.3, well within tolerance, but the reeding is not quite right, and has two sets of slash imperfections that wouldn't happen on a regular coin. I matched it with an 1862 and the color is paler, almost yellowy. Finally, the ring test. It clunked, but never rang. The 1862 rang clearly each time. Finally, that picture of the same coin counterfeit was the deal breaker. Mine is a duplicate. Fortunately I only paid $30.00 for it, so no big loss. I have a growing number of half dollar counterfeits, so this will be added. Thank you all for your thoughts and information. Bill.
