On the OP - I think that's at least AU55. I'd have to see it in hand (or much higher resolution pictures) to grade it along the MS61-MS65 slide rule. It's a nice example of the coin. Much better than mine.
I took a few more .. I only have and iPhone 5... Are these better? And would you be interested in the coin?
My grandmother remembered going over there as a girl, they lived in the Central Valley then, and remembers riding over the bridge in her father's Model T about a day after the first opening. She remembered that it closed a couple of times afterwards from high winds because the engineers were being cautious.
Note that the bridge on the coin is the San Francisco - Oakland Bay Bridge, not the more famous Golden Gate Bridge.
Ok sorry just read the rules... So if anyone wants to talk about my coin message me. I don't wanna Doug beat down.
To the original poster, based on the photo, your coin is MS63+/*. I've seen enough of these to know. I give it the + or * designation due to the great color luster and nice strike but it has too many hits to make it a 64. Also the coin Johni has is MS63 as well but only due to the terrible scratch going across the bear otherwise a much better grade.
