OK guys. I dug this today in a city park here in Indy. Looks like an Indian head penny, but it's 3" in diameter. Biggest penny I've ever seen and it looks like a real 1877 Indian head. So does anyone know what this is. I figure it's some kind of promotional recreation or something. It was reading 46-48 on the Xterra 705 with the 18.75 elliptical coil on and was about 5 inches deep in a limestone gravel walkway. I'm not sure how old the park is. At least 40 years that I'm aware of. But it could be much older. I thought at first it might be a survey marker, but upon closer scrutiny I thought it looked like an Indian Head penny. So I've had it soaking in white vinegar to try and get some of the crud off of it. Anybody have any ideas on what it might be? You can see by the pictures with the quarter in it, how large it is. If it truly was minted or struck in 1877 it would definitely be my oldest find. And it was kind of exciting even if it wasn't. Thanks for any input. Tom
