I have been hunting Lock 14 North on the Miami and Erie Canal for 7 years in Auglaize County, Ohio with permission. 2 Sawmills, a blacksmith shop, church, an Icehouse and many cabins sat on the property I have been hunting. I have found and continue to find many interesting artifacts on this property. Most of them are identifiable. However, I dug this unusual brooch, and I am wondering if anyone else has ever seen one or know why this would have even been produced.
