1960 DDO w/Blank planchet Reverse

[pennyhound]

This one should be an interesting coversational peice, to say the least.

New, 1960 DDO w/reverse die missing. (blank planchet reverse)

(Most prominent on Front of Lincoln's Portrait, from mid forehead to date, area and from Ear down thru coat, forward)

Coin's weight is: 3.0 grams even, well with-in torerance, so it's not a spilt planchet.

Reverse is completely smooth with no up-set were as the obverse has the up-set.


Would like to hear anything, anyone has to say, regarding this (maybe) new find as far as the DDO. (or anything else about the coin)

Again, awaiting any comments any of you may have.

First things first...the coin's reverse was ground and polished off. It is not a mint error. With the reverse completely flat and void of detail like that, it had to have been tampered with after it left the mint. Any genuine mint error would still show the upsetting at the rim and would show at least a mangled design on the reverse.

Second, it is not a doubled die. The profile doubling you are seeing is from reduction lathe doubling, pretty common in that era. The doubling on WE that you point out is on most if not all 1960 large date cents.

Hate to bear bad news, but that's the story.

Not bad news at all, but rather ...

Hey ... look at it like I do ... good news comes in strange ways at times, I learned something and just maybe alot of other people that come across this thread ... will also.

Ran across this one while getting that last bounce ready to ship and now, I know why I never listed it on me web page.

(really didn't know)

I didn't know and now I do ... still learning here.

Cheers

OK ... confussion setting back in ... just weighted a 2004 Lincoln Cent and it weighed: 2.5 !!!

What ... how can a penny that weighted 3.0 grams, with the reverse ground off, weight more than a penny that is complete ... help!

2004 (2.5g*) = 38.58 grs [38.58grs (+/-) 1.54grs] "within tolerence"

1960 (3g*) = 46.296 grs [48grs (+/-) 2grs] "within tolerence"
(- 1.704 grains ... Not enough, to remove all of reverse die, I would think.)


*1 Gram = 15.432 grains



Wouldn't a coin with the reverse removed (ground/polished off) be well out of tolerence on it's weight?

I don't know the specific answer to your question, but I can tell you two things...

1. 2004 cents are supposed to weigh less than 1960 cents. You're comparing apples and oranges.

2. Your 1960 cent has been tampered with outside the mint. There is no chance that could have been caused inside the mint.
