Flat Buttons, Barber & IHP from Old Baltimore Park

[Jamie1993]

Got a chance to hunt Saturday at a well hunted park in Baltimore City. I didn't expect to find much. I set the Nox 800 to Park 2, Sensitivity to 15 and Recovery speed to 6.
I listened for very low volume tones not paying attention to the VDI. I dug a lot of square head nails and bottle caps but the finds started to appear.
After four hours of digging i ended up with four flat buttons with shanks, a barber dime and 2 IHP. Hopefully some one can help me with two of the back marks on the buttons?

1886 IHP

1891 IHP

1892 Barber Dime

Robinson & Co. Flat Button

This the back mark I could use some help identifying. The Back mark is an eagle, 2 stars, Plated

Hopefully one of the button expert can help.
Comments are always appreciated. HH
