I have been digging zinc pennies at this site because I have found several IHPs, and was rewarded with another IHP - 1888. I certainly took a close look at the last eight. Unfortunately I can’t see any trace of a 7 under it. So it is not one of the valuable error coins from that year. 
However, I find the Defense Plant Corp. tag to be rather interesting. It reads “Prop. of Defense Plant Corp. an instrumentality of the United States Government WRI. CIN.” More letters were present in the lower left corner but only a C remains along with the serial number. The Defense Plant Corp. was a US government corporation from 1940 to 1945 basically in charge of funding war time factories. I wish there was some way of looking up the serial number on the tag to see on what kind of equipment it used to be mounted. Anyone have any ideas on that subject?
