Under Weight 2007-D Washington $
1 1

47 posts in this topic

The sound of this one jumped out at me when it hit the pile.  I also bounced it off the counter top and it sounds distinctively different compared to the other small dollar coins.  The coin sounds very tinny.  It looks like it has the same dimensions of a normal dollar.  The normal small dollars weigh about 8.1 grams.  This one is 6 grams.   

How common are under weight planchets?  Would this one be within tolerance?  Could it be the wrong planchet? Thanks.

Are the dimensions correct compared to other dollars?   That seems like too much weight difference to be within tolerance, but I do not know the mint weight specs for this coin.

I agree with your, to must weight difference tolerance point.  The mint weight specs for this coin is 8.1

The dimensions look and feel the same as other dollars. The coin might be slightly thinner.  Not sure exactly how to measure that accurately. 

I'm wondering if the planchet was suppose to be used for another coin...   I don't know.

I thought missing clad layer when I saw this but hard to tell from the pics.

You can't tell by these pictures but the Obv. looks like copper.

The golden dollars don't have clad layers do they? I think they are a solid alloy.

I think you're right.

Negative, they are totally clad. Inner layer pure copper, outer layers manganese brass. (thumbsu Since 2000, all $1 circulating coins have used the same planchet. If I remember correctly. :preach:

Can we see the rim? I don’t know about these manganese concoctions, but many times acid will disproportionately target the copper inner layer of clad coins. Just curious to see if that might be the case here.

Not sure if this is what you want to see. Hope it helps.  I can't see much of a difference.  Although, the edge lettering doesn't seem centered.

Something else.  I took the coin over to my brother-in-laws to show him.  I bounced it off his garnet countertop. The coin sounds like a cheap chuck e cheese token compared to all the other small dollars.

Sorry, but I’m beginning to suspect the scale. There is nothing here explaining a low weight. A hollowed out threaded coin?

The depth on the reverse looks wonky, as does the last edge pic. Does it really read “1N GOD…” instead of “IN GOD…”?

You mean a magicians coin.  Nope, it's not the answer.  That was the first place I looked.

I always wondered why they called them that.

Thanks for playing.

This thread is going nowhere fast!!  :roflmao:

It seems like it could be a missing clad layer based on the weight and some areas of striking weakness, but I would expect more weakness.  I can't tell from the edge pics if there are 2 layers (missing clad) or 3 (normal).  I'm leaning towards missing clad layer, but cannot say for certain

The photos look obvious to me that the obverse is copper colored and the obverse clad layer is missing.

 

The offset edge letters kind of confirm it.  But, I have not looked into how the edge lettering machine works on these.

 

BUT, I guess this could also be some kind of crazy acid etching post mint.

Does the unusual “depth” below the reverse rim bother anyone else? It seems to have an unusual look. And I do look at a lot of small dollar coins.

With that much weight missing, and no visual evidence of etching from and acid, I would strongly suspect a missing clad layer.

Coins are not weighed individually -- only in bulk. Same for the planchets. I suspect a defective planchet with internal copper oxide or a small void. Either would deaden the "ring" and still allow for a full dimension coin.

 

[I originally thought the coin had been struck using lower case edge lettering -- and thus "lighter." But that's not the case....]

OK...OK...the immediate above is just minor "humor."

Okay, so what's the point of this?

That is the legal specification. Occasional checking samples are taken, but most US circulation coins are "counted" by bulk weight....just as cents, nickels, etc. have been for a long time. Bulk weight is compared to strike counters on presses and weight of rejects. If the comparison shows an average correct weight, then the entire bulk amount is approved for release to Brinks and other counting/rolling companies and issued by the Federal Reserve System.
