It's definitely tricky!
When I saw the coin it was at $30 or so and I thought this is the old eagle. Then I looked at other coins, and became uncertain. There's some possibility of transitional eagles. Like eagle with one old wing and one new wing or old wings re-engraved into the new shape. At any rate, the next day it was it at $40, and I decided to put a snipe at double that price. And boy was I surprised when I saw how that auction ended.
P.S. The fact that there were at least 3 snipes above $100 is a convincing argument. While I was not certain enough to commit any significant amount. You were clearly not the only person who felt inclined to do so. This definitely sways my opinion towards the old eagle. I'll save the images for future reference.
