Quite often the ChipGuide uses the same picture for the primary picture when the only difference in a chip variation is a UV mark. That's done just for consistency, since all chips entered are supposed to have a picture of the entire chip. Occasionally, in the past, the submitter sent in only a picture of the UV mark, which was entered without an associated full-chip picture. Given a pic of just the UV mark, the admin might use the picture of the original chip since the only difference really is that UV mark. All else is the same -- color, mold, inserts, inlay, denom. You'll still find cases where a chip has only the pic of the UV mark, itself; those cases are becoming fewer, but still exist.

I see also that there appears to be a misconfiguration in the ChipGuide display of this particular chip. Normally, when chips are grouped into a series, only one chip is displayed with the others clickable under it. In this case, looks like two chips are displayed causing the chips to be displayed twice. That will be fixed soon.
