I will not offer my ideas about what this find is or is not...
But what I will say is that we are not dealing with layers of stratigraphy here. Every find from a CW site will not be Civil War. Likewise, not every rock from the field where native american artifacts were found is an artifact itself. A rusted iron tool found at a colonial site is not automatically colonial.
And even moreso when we're dealing with a copper bracelet (which does indeed look like a fantatastic find by the way) that was found over Seven Hundred Yards away.
What we find as detectorists and THers, it's up to us to be open minded enough to sort out. The fact that two items are found in close proximity does not mean that they're related to one another. One thing that continually amazes me in my 17+ years in this hobby is that just about anything can be found just about anywhere.
Part of the benefit of the "what is it" forum is that it takes the finds out of the finder's mind, puts them on the table objectively, and lets us all look at them independently of the specific circumstances under which each find was made.
In some cases, as with the scythe handle ferrule which was ID'ed in a thread of mine a while back, many folks had found the exact same relic. So I asked them to tell me what other finds were made at the sites where the items were found. I wanted to see if there were any similarities in the age of the other relics from the sites, or if there were some other find present which formed a common thread. But this is a rare case. Almost all of the tough whatzits posted here are single examples which are not well-represented in the posts of dug finds on this, or any forum. And yet thankfully in our internet age, and with a plethora of relic guides at our disposal in print, the objects usually speak for themselves.
So if part of the real value and strength of posting an object here for an ID is our ability to look at it for what it is--and is not--objectively, then I feel there is a two-fold, un-written agreement when the finder of the item posts it here. The first is that it is our duty as identifiers of these finds to look at each object objectively and do our best to figure out what it is. The second part of the agreement is that the original poster of the find should likewise be as objective as possible and let us try to help.
There is nothing worse than when a poster of a find wants to Push our thoughts in a certain direction because they just know it has to be this or that due to where a single isolated example was found, or "what was found with it."
In fact, when I post a Whatzit, I usually try to give as little information about where it was found as I can. I post good photos, dimensions of the item, and a description of anything that might not show up well in the photos. If I already have a hunch about what it is, I often keep it to myself to see if someone else thinks the same thing, or if I might actually be nuts for thinking it is X, Y, or Z.
I've noticed that when there are ill-feelings on threads in the "What is it?" threads, it is almost always due to one party or the other's decision to make the discussion subjective.
