1999 P Connecticut Quarter Plating Error

The plating on oberse is very thin also. Is this a common error? How much this quarter can be?

If this is gold plated is plated post mint and has a value of 25 cents. Quarters are not plated they are clad, that is a piece of copper sandwiched between 2 pieces of nickel/copper alloy.

Not, this is not gold plated, It's simply the color of the copper what seem on the reverse.

 

Carlos,

Like Richard said, quarters are clad, not plated. This is an important distinction. (On the other hand, zinc cents are plated with copper.)

If your quarter is missing a clad layer leaving the copper core exposed on one side it should be thinner and weigh less than a standard quarter. Also, being thinner, the details of the quarter may not strike up fully.

Recently I saw a New York quarter that was missing a clad layer. The reverse was copper. The quarter was the thickness of a dime and weighed much less than it should. The details on the obverse and reverse were only slightly weakly struck but the reeding on the edge of the coin was weak (because there was not enough metal between the dies to push out into the collar to fully form the reeding).

See if your coin displays any of these characteristics.

 

it sure looks gold plated to me...

I'd say not an error at all.

 

My scale is in home; this afternoon I'll check the weight, after work. This coin was found in change from the bank "Chase", the thickness is .072" at Rim, and .059" at flat faces inside. I'm mechanical Inspector, and I'm 100% sure this is not Gold Plated. Now... tell me what you see on the oberse. Because what I see is copper material, with silver plating on.

 

This is what a missing copper layer would look like

Think you meant to say "missing clad layer". That's a nice example. It looks like the New York I saw recently.

 

Just I putted my Quarter close to a piece of Bronze and they seem like the same material. How that can happen? After work I'll weight any way.

 

Weight is the real key. If the weight is correct then it is almost certainly merely a discoloration. This iscoloration can be evironmental, or in some cases it can be the result of copper dust in the annealing furnace becoming fused to the surface of the planchet.

 

Hi Carlos,

You have to Weigh it. The coin is not missing a clad layer. It is simply plated with something that we can't determine as the color in your pictures is not accurate. Or...it is unusually toned.
Plating is done in the thickness of atoms so it will not substantially add to the weight of the coin.

If the weight is close to normal....5.67 grams, then the coin is nothing unusual.

Thanks,
Bill

 

Good morning every body, I weighted the quarter along with a 2001 New York 5.6G; a 2005 Kansas 5.6G; 1965 5.6G and a 1990 5.6; and the weight of this is...5.8G There are two more pictures for other opinions. One is with a Real gold plated quarter, some body give me around 1987. and the other picture is with a washer from bronze (Machined) material.Thank again for your help. "I'm trying to post the pictures, but for some reason they are not going thru"; It's possible? that some body is blocking those.

 

If you put more attention in the oberse, that bronze material is UNDER a silver plating cover. And may-be that was the reason of the error. They believed was nickel cooper alloy. "my opinion only".

 

The slight added weight indicates that it is not missing a layer and in fact was plated or coated with something. It does rule out toning as toning would not impact the weight.

 

Because the color is too similar to Bronze, I order from the USmint a Bronze Medal "Van Buren's Liberty to make comparison; I weight all ready around 40 quarters from 1999, and also most of them are over-weight. I eliminated also some material from two of them, to see if they have different material than copper in the middle. I choice a very, very, very heavy one. but the answer was NOT, in the center is copper. I weight the 1965 gold plated and the weight was 5.5G. I believe was material mistake. As soon my Van Buren arrive I'll see if their are the same or not.

 

Are you sure your scale is properly calibrated?

 

I have several state quarters that look like that and it is environmental discoloration. I dipped one in Tarnex and the discoloration disappeared....

 

Trying to compare it to a bronze mint medal is a waste of time. Bronze can have many different colors depending the exact composition and whatever surface treatments the medal is exposed to. They can range from a pale yellow to a dark chocolate brown.

You've already shown from the weight that it isn't a missing clad layer. You are basically down to some kind of toning or enviornmental discoloration.

 

Hobo, about my scale; yes, I have that problem. Only show a decimal; yesterday I was in the internet also checking for a better scale. Any recommendation? and Thender; In my short memory I think I saw more quarters with that color, but most similar to the oberse of the 1999 than the reverse. There's almost green. Just took a picture of the rims I bring down yesterday, comparing with the 1999 Connecticut. On the top is a 1999 New Jersey, in the middle a 2005 Kansas.

 

Hi Carlos,

I am not sure what you are trying to show by exhibiting the edges. When a coin is plated, the edge gets plated as well. I can't tell what the color of the edge is from your picture.
Thanks,
Bill
