Hey thanks Antiquarian!
The little "coin" is actually a lapel pin with the pointy part missing from the back. It was so crusty I thought it was a nickel until I got home and saw the glint of gold. It really got me excited, even though I know gold usually comes out of the ground rather clean. It says "modern health crusader" on it, and is believe it's from 1920. I am including a photo example of what it would look like cleaned up.
The other little thing, my wife tells me, is part of a necklace. It's very light, unfortunately not any precious metal.
I was very happy with the Barber quarter, my 3rd ever. I dug carefully, but there was a big rock in the hole with the quarter and it got a bit scratched. Oh well, she's pretty smooth to begin with and I am not going to complain!
Thanks everybody for the kind replies.
