possably my best find yet, military button. help ID please

[Yucon Cornelius]

i have been hunting my parents yard for three summers now. his yard sets out close to the edge of a small town in illinois. This yard was once the site of a farm. It just keeps producing.
today was no different, on a couple hour hunt, i covered about a 6 square foot area. i found a brass hinge and then at about 6 to 8 inches i hit a nice signal right next to the driveway. after digging for 30 min through gravel and brick out popped this beauty. picture attached.
it appears to be an old military uniform button. the photo isnt the best, i only had my phone with me.
Details:
dia. 1 1/8 in
one small hoop on the back for attaching
on front:
eagle w/ wings spread
looks like a shield on its chest
a banner waves above each wing
with a round grest above that

What you have there is a Great Seal button. They became standard issue in 1902, and are generally labeled WW1 or WW2 buttons. Don't think about it as just a non-Civil War button, like a lot of people do. Remember that more than likely, the man that wore that uniform was still a man fighting for our country. I've found 2 Great Seal buttons, and they're in the same button case as my War of 1812 and Civil War era buttons. Great finds, keep at it!

Are you seriously saying that in 2 hours, you only moved forward two feet? How is it even possible to go that slow? What is that? 4 swings? Your sweep speed is 20-30min per swing? I just don't get that at all....
