Nice. Here's mine. Not nearly as high grade as yours, I guess, nor is it an unpublished variety. But I'm in it for less than $450 after certification fees. I think it was a good buy at that price. It is my only electrum coin, unless you count those little Japanese rectangles as electrum (which they sort of are, but not from naturally occurring electrum like the ancient Greek stuff is).
Your are correct. Lords coin as no laurel wreath on Attic Helmet. Plus seal is very bold. Mine looks more like Triton XIX / Roma III 213/ but slight diff. weight/ wear. According to CNG 4 known of type.
