hey CMD, the good news about your rings is that they pre-date the machine age, since they are clearly hand-worked. Loosely speaking, that would place their manufacture prior to 1840 or so, and most likely prior to 1800. Good relics, for the States.
They are quite possibly contemporary with that KG copper (early 18th Century) or even perhaps earlier. The source of materials for manufacturing bronze (if that's what they are) was limited either to British imports, or to a couple of early Dutch copper mines in New Jersey dating to the 1600's. Furthermore, the tin needed for bronze would almost certainly have had to come from Cornwall (England). In other words, that stuff didn't exactly grow on trees in Jersey, and the Jerseymen would have been much more likely to make rings out of forged iron, as bog iron ore was still relatively plentiful back then.
That one ring does look as though it could be iron. The early iron from NJ seems to get a nice black oxide, not that caked stuff, because of the high quality of the iron ore used (and probably the forging techniques). Either way, it looks like the piece has been hand-worked.
If bronze, your rings were likely brought over on a ship in the Colonial period. That is not "old" to our British friends on here, but then again, neither are the KG coppers that we try to find.
That other object in CONSTANTINVS's picture there,the pointy one, has no modern counterpart that I know of, and thus my find of such an item could quite possibly be a genuine 200-150 BC relic... especially since I did find a very worn, ancient coin within 10 feet of it.
So basically, it looks like those dogs were messin' with ya, just like I warned you. Your evil plan backfired.
