Boy was it a hot muggy one too!
Ron and I met up with Jim Atkiv (who is retired and detecting almost every day now ;)) in the norther corner of Massachusetts , its been so long since i've gotten out I almost forgot how the deus sounded 😁 . Ron did well with almost a dozen buttons at the few...
NC is rich in history and a beautiful state , I myself visit the north western (around Jonesville) once or twice a year to spend with family , detect and arrow head hunt . I may even move down there in a couple of years permanently . I wish you the best of luck.
Dave have you ever use media blasting (sand or soda or other) to remove the heavy rust ? i would steer clear of this method if the item was very thin or delicate iron but i've used it on gun barrels and tools and its a lot quicker , less messy and has similar results ?
Clean the back as best you can and show us ( i suspect it has a solder or brazed mark where the attachment was) it could be a few things like a cufflink button , tie tack or lapel pin .
just the highlights of a hunt this past Friday with HEAVYMETALNUT (Dave) , a better than average Matron head and a couple of really nice "open work" colonial buttons .The weather is starting to cooperate ... get out there and get some !Dan
