I also have this one, which I consider one of the most attractive coins I own.The detail is amazing!

I actually was in a little group that worked to help Carr with the final design for the Amero coins. The first two are some designs I submitted, and the last two are the final coin designs.

The basic design was Carr, and the stars were my addition for a background. Neither one made the final design. 

It was a fun experience though.

The last two photos are of my coins..

Numismedia has the 1951 Proof set valued at $720 currently.

So $409 is not off for a real auction price. It may go even higher.

A little too aggressive ( in that area)  on a die polish would be my guess. 

While the real VDB initials were shifted a little to the left of center, the ones you are showing seem to be too far to the left.

Just an observation.

Question: Why didn't you just send the coin to PCGS for a re-holdering?

All the holder issues would be gone then, and the grade would be protected. (except for the CAC bean) Not sure how they handle a reholdering.

Hate to be the odd man here, but that looks like post mint damage to me.
