I would definately give it a VF20. Most of the wing detail is there, the vertical lines on the reverse are present and the braches are clear.
A Very or Extremely Fine Mercury If you search eBay for "slabbed" Mercury dimes, I believe you'll find most will grade a comparable coin as Very Fine, and I'm certain you can locate comparable PCGS coins, certified as Extremely Fine. I would technically grade the coin VF30 reverse. Rich :thumb:
