sacagawea dollar

I found two sacagawea dollars that are different than all others that I have seen and I was wondering if anyone could help to tell me what kind of an error it is. One of them is the same size as the sacagawea dollar but it is silver in color and the other one is the same size as a sacagawea dollar but it is thinner and one side is normal with the gold and the other side is copper in color. This coin also sounds different when tapped on something.

can you post any pictures?

 

sorry but I don't have a camara to post any pictures.

 

How about a scanner?

 

I tried my scanner and the coins wouldnt show up.

 

The one looks like it was struck on a sba planchet but I think that someone just somehow took off the gold layer on it and the other one I still dont know what kind of error it would be because it isnt as thick as a normal sacagawea dollar but is the same diamiter as a normal sacagawea dollar and it has one side that is copper in color

 

I could try to weigh them when I go back to work on Monday.

 

The silver-colored Sac dollar is probably plated, unless you can see the copper core on the edge. If you can see the copper core, then it might be struck on an SBA planchet, and would therefore be worth about $10k. The other coin might be missing a clad layer and would be worth several hundred dollars.

 

I can see the copper layer on the edge of the coin. And would it be alot thinner if it was only missing the clad layer because it is about 1/4 smaller than a regular sacagawea dollar. thanks mike

 

Now, that's very interesting. There is now a chance that you've got a rare and very valuable "transitional error". Since weight, diameter, and density are the same between Sac dollars and SBA dollars, the coin will have to be subjected to an SEM/X-ray spectroscopic analysis. I suggest you send it to a reputable grading service and pay the extra $100 or so for this test.

As to the Sac dollar with the possible missing clad layer, it should indeed be thinner than normal. I don't know offhand how much a Sac clad layer weighs, but it should be well over a gram, since that's how much a quarter clad layer weighs. Therefore the coin should weigh less than 7.1 grams (normal weight is 8.1 grams).

 

I got a camera today so im going to try to post some pictures. The coin on the left is a normal sac and the coin on the left is the error.

which left was the error? just kidding.
hey i could not see the photos, all i got was a sign in page for aol?

sorry,

The color of the suspected missing clad Sac is pretty convincing. The design is crisp, which would seem to rule out a clad layer removed by acid. However, one should never rely on color alone. As I said, you need to weigh the coin.

 

I went to a coin dealer and he told me that the one that is silver was probaly dipped in acid and the other one is missing the clad layer. Thanks for all your help Mike

 

The average coin dealer knows next to nothing about errors, and therefore, any opinions issuing from such a source are to be disregarded. If the dealer did not weigh your possible missing clad error, then you still don't have an answer. As to your other coin, an acid bath will not turn a Sac dollar the color of an SBA dollar, and certainly would not do so without affecting the core as well.

 

i went to another coin dealer today and he weighed the coins. The one with the copper on the back is 2 grams less and the one that is silver in color is the normal weight.

 

Good deal. Your missing clad error is legit. Nice find. The status of the other coin is still indeterminate. As I mentioned, the weight of a Sac dollar, SBA dollar, and Sac dollar struck on an SBA planchet will be the same.
