Correct answer Jill_C

Apparently you photographed them on a black background, then cut them out to place on a white background; the masking effort was insufficient as the black background can be seen clearly around all the edges.

Thanks to everyone for their kind inputs.  I do use a copy stand and a remote shutter trigger for photographing coins; but perhaps the lens was not perfectly parallel.  Also these coins were made 2,000 years ago and there was presumably no effort made to keep the surface of the coin parallel, so I guess one needs to rely more on dept of field than the level of the suurface of the macro lens to ensure a uniform focus. 

 

Thanks again - I am going to rephotograph the coins bearing in mind all the comments.

It is quite interesting to note how irregular and "hand-made" they look, and I think with a bit more work you'll be able to properly capture that aspect. They must be quite valuable too !

As @Jill_C mentioned you'll need to clean up around the coins better to remove the blue / black background.  Also, to the right of the right coin, there are some artifacts left as well on the white background.  Take a look at 100% magnification.

    Rob's close-up also reveals a lack of uniform focus; if you're going to reshoot these, the camera must be on a tripod with the lens directly parallel to the surface.

        Many thanks for any help in diagnosing the technical issues that cause the Adobe Stock moderators to reject them.  My intent is to correct any issues and resubmit them.
