I found a 1972 Philadelphia mint Lincoln Memorial cent that I believe is a double die variety error. But the most exciting part is that the coin weighs 3.48 grams. I checked and rechecked and the weight is accurate. I have been unable to find any planchet that fits this weight range. Could it just be a heavy copper planchet, or a foreign one? My gut is fluttering at the possibility that I possess a unique error coin with no previously assessed value, but my head is telling me it's nothing special. Help please.    Edited by MisterPenny039

@MP039, first welcome to CCF. Second, I agree that adding some pics to this thread would help. If produced to within the mint's tolerances, I think that your cent should weigh no more than 3.11 + 0.12 = 3.24 g.

Show the coin also with a normal copper planchet showing the edges of the two different coins. That way we can see the thickness of a normal and this coin to see if it is the issue. Kind of like this:  That way we can see both edges of the coins. |

I'm not seeing any hub doubling. On the 1972 plain cents you can usually look at the '9' on the date and you will note they have the same type of distortion on them:  |

First, I was mistaken about the mint. It is a Denver. And the main subject I need information on is the weight discrepancy. I posted a pic with 3 coins stacked up, the penny in question is the one in the center. There is virtually no difference in the thickness of the 3 coins pictured. The "bread" of the sandwich are both 1972's of normal weight. The possibility of it having hub doubling or a Cud or whatever I will resolve if and when I send it in for certification. Thanks everybody for your input. |

Just a quick note,the center cent looks kinda pinkish to me. That most often means it was harshly cleaned and if you have it slabbed it will get a "details" designation. John1 |

I am aware that it has been cleaned. Upon further inspection it appears like the anomaly coming off the back of the 9 could possibly be a "D" mint mark that was stamped over with the date. The shape and the vertical alignment are what makes me think this. Any thoughts?

Upon closer inspection it appears like there may be another d mintmark coming off the back of the 9 in the date. Any opinions?  |

Quick and easy answer concerning weight is blank was punch out of rolled thick stock. More food for thought. I see the Denver mint was producing foreign coinage in 1972. Though some show potential similarities in composition, I see none of the raw (punched) foreign blanks match the weight and or diameter needed to strike in a US cent collar. That said the potential that the wrong stock (thickness) meant for foreign coinage was present to punch blanks for US cents. To prove or disprove this possibility or theory requires some math skills that I yet to reliably conquer. Thanks, Doug. Quote:
