In my professional opinion, the following item is:

2006-W AMERICAN GOLD EAGLE 4-COIN PROOF SET.  Includes 1 oz, 1/2 oz, 1/4 oz & 1/10th oz Gold Coins.   All Brilliant Proofs with very nice frosty devices and deep mirror fields. 

This one has a particularly nice surface, and may be a good candidate for 3rd party grading if you are so inclined.

With original mint packaging and Certificate of Authenticity.  Struck by the U.S. Mint. (Note: this is a slight tape scuff on the front of the box).

All gold items are carefully checked for authenticity by my Verifier Pro.  Then, the item will be placed in a thin plastic holder.  You are invited to check it (preferably with a Verifier Pro if you have access).  Once you are convinced that the item is authentic, then you may remove from the protective plastic and place in the hard plastic capsule.  Once the item is removed from the thin plastic holder, it is not returnable for any reason.  

Note: for maximum security this item may be sent by U.S. Registered Mail.  This will likely cause a week or so extra time for delivery.  Please be patient.  I want to make sure your item arrives safely.  

Total 1.85 Oz of Gold content. (.9167 fine, with 3% silver and small amount copper) 

Gold Bullion value alone as of 5/16/24 is $4401.33
