Authentic or Reproduction Antonio

By request, I thought I would list a couple items listed on ebay that - to me - are questionable. Here is my opinion on 4 alleged Authentic Antonio Pineda - 3 bracelets and a necklace.
Above, is the necklace with an opening bid of $800. A similar necklace from about a year ago closed at around $3,000 - I remember cuz I was a low bidder - tho it was a bit over my little budget...
All four pieces do have the 970, Antonio crown mark, spread eagle with 17.
Now check all four items for a YY or ZZ mark on any of these items. There are absent, not there, missing.
Antonio also usually had design numbers on his pieces as well. Also, not present.

Now the mark pictured above with the eagle looks a bit hinkey to me...too wingy or something.
Additionally, one of the item location is Thailand - the others are in Paris...same seller. When I looked at the sellers feed back about a week ago, it was zero. Now its over 50.

When I first these pieces I was impressed but on closer examination, I'm not that sure. Now, I havent seen them and not handled them and I could be dead wrong. But this time around I probably wont be pulling out my ebay charge card...
Shop carefully and compare markings.

Here is what I think is good or authentic mark - note the YY and partial design number - this is from the Cross pendant necklace with moonstone hanging from velevet cord.
