1904 Eagle

Those fine scratches are called Hairlines and they indicate that some kind of abrasive cleaning was performed. They actually don't look too bad in your photo; they can be much worse. If they are in fact "very noticeable" then the major grading services (PCGS or NGC) would not grade the coin.

The coin appears to be lightly circulated and I would estimate the grade at AU-50 to AU-55. The 1904 is a common coin and does not carry much premium beyond its gold content, unless it's mint state. I don't think it would be worth having your coin graded since even if it did grade as an AU-55 it would still sell for about the same price as a raw (ungraded) AU coin.

Jaobler is right. Its "looks" like an AU. Just to be sure you might want to take it to a coin shop (a good one or maybe two) just to get their opinion. I always hate trying to grade purely by photos. I can make one of my MS62 half eagles look so much better with a photo than it does in real life. In fact the one I have in the registry looks like it has tons of luster but it is pretty dull. I did not even try to make it look that way..lol I noted it in the description just to be far
