Josh,
You should be able to determine if this one is UNC or AU. Look closely at the highest points of the design for mint luster. That's the "frost" created during the minting process. If it remains intact on the highest surfaces, your coin is UNC. If it is shiny on on those high spots in contrast to frosted lower areas, the coin has seen some mild handling and will probably grade AU. Look at it from an angle rather than straight-on and rotate it in the light so you can clearly see the luster. The highest points on the design for this series are the hair above Liberty's ear and the top of the hair band on the obverse. On the reverse it's the breast feathers and leading edge of the wings.
Unfortunately the 1907 is a common date for the series and just stays ahead of melt values in grades below MS63.
