I cant say of the origin but they do look like reproductions to me when I look close at them.
Ebay is notorious for reproduction sales both as reproductions and labelled as authentic with bogus, cheap toilet paper COA's not worth the time to read.
There are a few individuals who apparently make income off of papering, what to me, is questionable, sometimes obvious, fakes. One rarely sees a COA from them at any reputable relic show or auction. They are in the shadow world of rip-off and slight of hand. Make a sale and be gone. Return policy are often not attainable for a number of reasons.
The funny things is nobody seems to name them all - and so unknowingly they continue to get business by others who are of questionably reputation or the new collectors who just dont know any better, or for some other reason I cant seem to understand.
