Bi-Metal error coin?

This is my first post here and I wanted to be sure the photos are uploading and viewable on this forum without members having to click or download anything in order to view the photos. The uptick in confirmed rare mineral and unconventional metal combinations being utilized is what leads me to consider there is possibly more than a "coin artist's" work at hand. There are other anomalies in addition to the bi-metal which is not the effect of light and angle. Please advise if the photo appear or if a link appears -thank you!

Welcome to the forum. No, not bimetalism, lingering luster. The photo appears.
Not sure what exactly to look at. Perhaps you can post a whole image of both obverse and reverse?
The variation of color? across the upper eagle wing... could be result of dipping into something?
Welcome to the forum.
I must have missed the news about this uptick.
you have to be careful with the terms. bimetallic means something like this:

Just toning.
that variation is oxidation colors

The coin's physical makeup is a three-layer clad construction - pure copper sandwiched between outer layers of manganese brass.
that effect you see is not the copper showing through
Thank you. I wanted to be sure the eye and closeup photos would upload before adding more photos. The irises are copper-amber with contrasting white metal in the eye field. Initially, I thought the bimetallic appearance was some type of painting/plating (I can't fathom why anyone would do)
when other anomalies stood out, eg: a circular ridge protrusion around the eye of the expected composition along with particular striations in the field I'd seen in prototype errors /rinse errors Mike Byers wrote about. I would attach a link to Mr Byer's however his listing of a Washington Quarter on a Sacagawea planchet, which exhibited the same type of grey-transparent veil-ray like striation running all over the field and devices, is no longer listed.
Add to this, the reverse, exhibits textured feathers in what should otherwise be relatively smooth, such as the tail, secondaries and primary feathers.
😵💫
It's a normal Sacagawea Dollar with traces of original luster in recessed areas.
First time I think we've seen an "error" coin specifically attributed to @Byers and not YouTube or eBay.

there is nothing grey-transparent
While you might not like the answers you’ve received, clearly, the coin isn’t what you thought or hoped it was. Additional images and/or observations aren’t going to change that.

It is just a common $1 coin.
You have a Sacagawea on a Sacagawea planchet.
