I searched a bag of gold dollars and came across this coin. At first I thought it was plated, after taking a second look I see no evidence of plating. It appears the gold layer is gone. There are areas of the coin on the lettering that gold color is intact. What do you all think?

Looks plated to me

It is plated. The golden areas are where the plating is gone.
The remaining remnants of the gold color does appear to be pmd. Buffed off or something. IMO. Peace Roy

You can see on Liberty's nuckles where it was scuffed the gold color underneath the silver colored plating.
"When they can't find anything wrong with you, they create it!"
That is what I thought too, and it could very well be, if that is the case one would see damage on the whole coin. I took a Sac, dollar and used my zooltool to attempt to duplicate that thought. I just used the Rim of the coin and learned there is a silver colored layer under the gold layer. If someone buffed off the gold layer I believe there would be more evidence of buffing, Here is the photo of the buffed off edge. Under the microscope it clearly shows 3 layers on a gold dollar. I don't see the usual mirco bubbles i have seen on other plated coins on the obverse and reverse.
Not stating you all are not correct. Based on this experiment there is no way someone buffed off the gold layer. IF it were buffed it would show evidence on the coin. Plated still an option. Investigation continues. The coin weighs 8.1 Grams
There is no silver-colored layer of metal in a regular presidential dollar. That means that someone couldn’t buff away a gold-colored layer to reveal a silver-colored layer underneath.
When a presidential dollar, or Sacagawea dollar is missing a layer, it usually reveals a darker copper color underneath.
This coin was plated silver (or some other white metal) and has since circulated, causing the original gold color to be revealed on the high points.
That is what I thought until I used my zooltool to buff the edge of a sac dollar and it shows 3 colors. The weight matches other gold colored coins. If its plated it should weigh more, if the gold layer is missing it should weigh less correct? I weighed it 5 times 3 out of 5 times it came to 8.1. Weights 7.9, 8.1, 8.0, 8.1, 8.1 so I went with the last weight.
Pres Dollars with clad layer missing will be about 6.0 g.

So I decided to rub on the Reverse edge of the coin with a plastic sanding file, which I hate to do, because I didn't want to damage it more. and It showed a gold layer under the Plating. Yes upon further investigation I believe this is a plated coin. Darn I thought for sure I would see those micro bubbles on a plated coin. Learning every day. So all of you who stated this is PMD Plating. Pat yourselfs on the back. Good Job. Just keeping you all on your toes.
I am glad to see you finally convinced yourself that the experts here were correct. Cheers, RickO
This is UNTRUE. Plating is atomically thin and will add no measurable weight to the coin to the nearest 0.1 grams.
Agree. Modern plating techniques can apply it just a few molecules thick.
This coin's status was obvious; OP just needed to be convinced.

FWIW that damage that is on the letters and concentric with the edge is from a coin rolling machine.

Sure Rick the same experts that stated my quarter was PMD, Yet Mike Diamond Coin World Magazine may think otherwise. You may think their experts; I haven't been impressed by most of you here. There are a few good people here and you are not one of them. Just my opinion. You think your snide comments are cute you just come off as a jerk. Just most here won't stand up to you. Clown!
Why do you keep posting here..... you are free to go away if you don't like the people here.
Don't let the door hit ya in the ass on your way out.
Just an FYI for @arby96 as an expert you should know that there is absolutely no gold in the coin.
Nope, no gold, not even plate.

DUH when one refers to gold on these coins, its the gold colored layer. Wow!!!
You just keep reinforcing the first impressions you made back when you started posting.
Your post has been reported and I hope the moderators take notice.
P.S. - it seems you've finally figured out how to properly use the words "me" and "my".
Dude is just out of line. Buh bye.

I assure you that Mike Diamond, when he gets either the photos or the coin,
will agree with the consensus.

Wow OK..
I took a look at several of your recent posts and see no instance of people being uncivil towards you.
@ricko is easily one of the nicest guys around here.

Me do that on purpose, Me like to use Me instead of I. This has to be the worse coin website Me has had to deal with. Me first impression of a site that does not encourage postitve learning enviorment. This site has too many who think their smarter than eveyone else and prejudges individuals for posting coins they believe is beneath them. Thank you for reporting me. If the owners of this site tolerate individuals like you and Ricko who think its cute to make snide coments its not a very welcoming place to post coins. That is why me never refer anyone to post here. Yet me will not run away from bullies like you all. So if the owners don't see what going on shame on them.
Because I don't runaway from bullies.!!!
Please please please throw in some profanities to make the decision easier. 😀
And I see that your assessment of people is as bad as it is of coins.
If I were to make a list of words that describe Ricko, "clown" would be nowhere on it.
Ricko Quote "I am glad to see you finally convinced yourself that the experts here were correct. Cheers, RickO"
Rude and totally unnessary. I stick by Clown!!!
We will see, you could be correct, you also could be wrong. Hope that doesn't hurt ya''lls pride too much. Would love to see all of you eat crow. What a clickish site. You all act like a bunch of mean girls. Its truly amusing.
When digging really deep holes you'll find that long-handled shovels are the best.
Contrary to what twitter and facebook might have you believe, not everyone on the internet is out there to argue and put people down. No one here is bullying you.
Which quarter are you referring to above? You have posted a lot of them on here.

Rickos Quote "I am glad to see you finally convinced yourself that the experts here were correct. Cheers, RickO" Unnecessary. not Conducive to learning, Unsolicited, and plan rude. No comment was made by me until Ricko had to make a snide reply, What is crazy you are all so star struck you can't see it or refuse to see it. Individual come to sites like this to learn and better understand this hobby. Individuals like Ricko who post these type of comments give sites like this a bad name. The word is out there about the going on by some here. Like Me stated very Clickish!!
Me believe there is a way to block me, so if you don't want to see me post please feel free to use that option. Me, I stand my ground and don't tolerate individuals who make snide comments, there is no place for that on site like this where learning should be taking place. Just because one might post a coin someone doesn't like or agree with, one shouldn't throw out sinde rude comments. Its truly a sad state of afairs this happens here.
