Thanks fellas! Great info! Coincidentally, I found a tombac today (pictured), this one rang up high 50s at 7in and solid 60 out of the ground. They always crack like that...I cleaned that one spot, which really looks like the metal in the brooch but rings up very differently. So Dave, you're right, ours must be from England...and that's why I believe the brooch is some type of bronzy silver as it rang up at 87.
Dan, it was on the banner years ago. Thanks!!
