For the record, Jim is a long-time dealer whose primary focus is Civil War.
Jim Hayes stated that he did not issue COAs for the items in question, and further noted that his COAs are notarized.
To my knowledge, there have been no images of the COAs in question, so this supports the contention they may not be legitimate.
Until someone can produce a notarized COA signed by Jim, I would consider these COAs to be bogus and not originating from the known UACC dealer, Jim Hayes.
