I recently purchased my third 1874-CC
Trade dollar -- the first two were both counterfeits. One of the areas that I check when examining a
Trade dollar is the eagle's eye. My understanding is that it should look like this.

The eye on this coin looks like this.

I immediately assumed this was another counterfeit. It weighed 26.9 grams which I felt was just slightly too light for a coin with almost no wear. The seller swears the coin is genuine so I agreed to have it certified. The coin is at ANACS right now. Yesterday, I received an 1876-S
Trade dollar and it has the same round eye. I looked on the PCGS web site where they show the photogrades for
Trade dollars. I was surprised to find that the MS 67 example also has a round eye. Now I'm wondering if maybe these two coins are OK. I'll be sending the 1876-S in for certification as well. Does anyone have any information about the round eye vs. half-closed eye?
