Question about a 2007 John Adams Proof coin...

    So I found a 2007 John Adams Proof Dollar today at work (Had the mirror fields, satin obverse/reverse high point details, and S mint mark on the edge) but there's something off about it, in equal spaces, there are 3 little 'bump' lines that separate the coins edge into three equal portions. Now I know the first series of the small gold dollars with edge lettering had a few errors in them, my question is:

    Is this a known error? Or anything else that is legit and possibly expected...
    Or, is it casting marks... Making this a fake...

    Are the regular dots there? Two of them for 2007.

    Bigger picture please. Edge lettering on the proofs was done differently than on the non-proofs. On the proofs the edge lettering happend at the same time the obv and rev were struck. Perhaps the collar was segmented (3 segments) and the "lines" are actual gaps between the segments?

    Since they are bump lines (i.e. raised, not incuse), it makes sense that it is the gap between segments.

    Where are the 3 "bump lines" in relation to the date, "e pluribus unum" and "in god we trust"?

    That's about the best picture I can get with my phone, but I do see two same sized dots in different spaces on the edge...

    Hmmm, that's normal dot spacing. I'm sticking with my theory about a gap between segments. No idea if this is right. No idea if it is a known "variety" or whatever either. Tomorrow, more knowledgeable people will chime in.

    I just wanted to know if it's right because I have a small collection of the golden dollars (About 125) but none have had three ridges on the coin... If the collar was indeed segmented this makes sense as I believe this edge lettering was new for the mint anyway so perhaps the collar wasn't tight enough and some metal seeped through...

    I have read that segmented collars were used for circulation (P, D) coins starting in 2009. Before that (i.e. 2007-2008) the edge lettering was done diffrently (not with collar) for circulation coins. BUT, the 2007-2008 PROOFS had edge lettering done with colllars. 'nuf said. Wait for more knowledgeable.

    Aha, so ridges are to be expected... Nice...
    Plus it's another thing distinguishing the Proofs from the Business strikes as the business strikes don't have the ridges...
