My last find at Memorial Park, Houston

[The Beep Goes On]

During my hiatus from the hobby I detected Memorial Park at some point - I detected occasionally, but never posted, etc. It is now expressly illegal to metal detect there now. I was looking through the finds collected during this period and this one was the only historical item. I found some silver coins in Wyoming at the site of our burned down ranch house, but those were the only other notable finds. The button is a WW I US Army Model 1912/17 Service Coat Button.
