Opinions if this is a clad error state quarter

Hey, I'm new here and wanted to see some opinions on whether this is a clad error coin. I work as a server, saw this in one of my tips, and was kind of excited. I know the normal weight is supposed to be 5.67gms, and this one weighs 5.508gms. Also, if the opinion is yes, should I submit it to PCGS to get authenticated?

Most likely it's environmental damage from being lost in the dirt.

Missing clad is rare. Missing both layers is very very rare. ED is much more likely.

Weigh it - to 0.1 or 0.01 grams - if it's really missing clad it will be out of spec.

 

Iam only going to guess and see if ive been actually learning, lol. Iam going to lean towards eviromental damage.

 

Thanks for your reply , it weighs 5.508 gms, I know the "normal" weight is supposed to be 5.67 gms. That's the main reason for the post. The edges don't have even the slightest sign of it ever being plated with the outer layer. I would think that there would be some sign of it.

 

It's environmentally damaged but the sandy patina makes it look like an ancient coin.

 

That is definitely Environmental Damage. Clad is a mixture of copper and nickel. Cupro-Nickel is what it is called. Long exposure to the elements will darken the surface on both sides..

Here are examples of my metal detected coins -

Even nickels suffer the same environmental punishment.

 

Hey, I'm sorry, I calculated incorrectly, it is 82 gn, which converts to 5.378 gms.

 

I appreciate all the replies, it's great to have the feeling of joining a community that is knowledgeable, and will respond so quickly. Thank you, guess I got a little excited that I might have possibly found a double clad error.

 

Here is my 2001-D Kennedy that is actually missing the reverse clad layer.

Right, @Cheech9712 !

 

I can definitely see the difference, I know my quarter is not MS. I don't want to dip, or clean it to rid it of the residue from being in circulation, that was my reason for posting weight, and the photos. Felt like a little kid when I thought I might have found a really scarce coin. I'm that guy at the register looking at every coin in the drawer lol

 

Sorry - missed that you posted a weight. I also see you redid the calculations...

5.508gm would be within mint tolerance which is 5.67 ± 0.227gm.

Note that except for precious metal, tolerance is a 95% item - so 5% of coins could be below 5.443 or above 5.897

One thing - coins are clad not plated. The three layers (copper-nickel outer and pure copper middle) are mechanically bonded - TONS of pressure.

 

Yeah, Actually calculated wrong, posted a new picture showing that it weighs 82 gn, which calculates to 5.378 gms, and sorry for my mistake in saying "plated". I really appreciate your expertise, and information . I'm going to go buy a gumball lol

 

Only if you have your own machine in the ManCave!

 

By the way, welcome to the neighborhood, Marc! ~ Chris

 

Thats right folks. It's real. Now there's more of those 1933 gold 20 dollar coins then this one

I doubt that scale is accurate to .001 gram.
