I thought the 2000 P looked like a good candidate for the rinse. What do you guys think? I don't have them in hand yet but I can post better photos when I do.

I think the lighting used for the photo is making that coin appear to be a different color than it really is. My guess is that it will look the same as the other ordinary Sac dollars once you see it in hand.

Thanks, It wouldn't be the first time I've been fooled by photos, so we'll see.
Your coin’s surface should have a sheen/reflectiveness to it if it has the experimental rinse. Think of it as that dark area having full cartwheel luster.
It’s somewhat tough to judge from your photos, but appears to be a dull muted look to the surfaces, making it more likely a tone or circulation effect that caused the darkness, not experimental rinse. It’s even possible your coin has been improperly annealed, which causes the darker color but gives the “dry” look to the surface.
thanks for the input and help, those pics i did with a scanner, i tried to get better ones with the phone, not sure if it changes anything for the better, lol
Those most recent photos above are not of an experimental rinse dollar in my opinion.
environmental damage of some type, but not a mint product from what I see in the photos

Here's another page from Mike's website showing the SEGS slab.
The CoinWorld article indicates that Mike had these slabbed by Larry Briggs of SEGS.
I wonder how many of these are still in their original SEGS holders? Anyone see one recently?

I think your odds are astronomically low. Looks like dark toning, nothing more

I think this article contains info on the chemicals used by the mint on these experimental rinse coins

It involves this and similar versions of Carboshield

Carboshield BTX was the form of Carboshield they used at the mint.
