1954-d 2.5 grams

fnetty · March 6, 2013 3:37AM

I have a 1954-d cent that has a sound like silver but is all copper in color and same size as a cent but weighs 2.5 grams. I never posted on here and put links below for the pictures I hope they go thru. Does anyone have any thoughts. Thanks

Looks like a thin planchet to me.

Denver did not produce any foreign coins or planchets between 1949 and 1967, so we have either a rolled-thin planchet or a split planchet. Since I don't see any roughness on either side, I will go with rolled-thin.

Worn, thin planchet would be my guess too. Not sure what to make of "sounds like silver".

I was wondering about the foreign planchent didn't know they didn't make those for that date Thanks for the insight.

Rings like silver, weighs the same as a dime, the color in the picture doesn't look like copper. Could it be struck on a dime planchet?

Looks to be normal diameter. I don't think that a dime planchet that weakly struck could pancake out to full diameter.

A specific gravity test would be helpful in eliminating the possibility.

For what ever reason it happened, error on the roller settings, lamination peeled off during rolling, etc. so I'm in the thin planchet group.

Over the years I have seen coins struck on "tapered thin" blanks that were assumed to have been punched out of the beginnings or endings of planchet strips where the metal was fading away. It is possible that something like this was punched from the beginning of the fade. It does seem to be a bit weaker at the top of the obverse.

Maybe it is silver--smoeone copper plated it to make it look right.

I did a gravity test with the coin and my results were 0.2 grams in water suspended. I also tried a silver dime and came up with the same number 0.2 grams don't know what that means exactly.
Thanks for the welcome

I don't understand those numbers.

A copper cent should have a specific gravity of 8.8. I would expect 2.5 grams of this alloy to displace .284 grams of water or read .284 grams lighter while suspended in water.

A silver dime has a specific gravity of 10.3 and should displace .243 grams of water or read .243 grams lighter while suspended in water.

EDIT: Oh my gosh, I misplaced the decimal point. Now fixed.

fnetty · March 10, 2013 1:12PM

maybe I did the test wrong. When I cleared the scale with the water in a cup and submerged it the reading was 0.2 grams in the water.

CaptHenway · March 10, 2013 1:51PM

How are you suspending the coin in the water? If you are using a piece of bent wire, the end of the wire may be touching the bottom of the cup.

Describe your apparatusand procedure and we'll see if we can figure out where the problem is.

fnetty · March 10, 2013 11:27PM

I tied the coin with thread and filled water in a cup. Cleared the scale and submerged the coin. The readings were 0.2 dwt, 0.3 grams, and 0.01 oz.

CaptHenway · March 11, 2013 12:06AM

Describe your complete setup.

What type of scale? Triple-beam with slide weights?

How are the readings given? In pennyweights? To how many decimal points?

Are you sure the coin was not resting on the bottom?

Mornin' All -

As Tom mentioned in his earlier post,
it's a Rolled Thin Planchet.....not a
wrong planchet or foreign plan, etc.

These are common for the 50's thru
the end of the copper series; I'd say
that Denver Mint rolled thin cents are
somewhat scarcer than those from
Philly......
