I know what you mean. I am lucky enough to have two spots that have both artifacts and old metal things. One is a old one room school that a modern home was built around it. The other one was built in 1847 with continuous occupancy until the late 1980’s.
Row 1, number two, and row 2, number 2 look like Reed's Spring camo flint. Row 2, number 1 could be Pierson or heated Burlington. Three other Burlingtons and a couple I don't recognize. How'd I do? Gary
