While there were many CWT's of which copies were made, the subject specimen looks genuine to me. The majority of copies that I've seen, not restrikes from original dies, were cast from common dies. Typically, the surfaces of the copies exhibit a granular look that can be mistaken at times for ED - environmental damage. The copies were mostly made and marketed in the 1960's and later as public interest in the centennial of the Civil War grew; this, given increasing media attention. As original Civil War tokens were relatively inexpensive back then, traded at about a dollar, each, the copies didn't seem to achieve much commercial success for their makers ... fortunately!
