I have a 1951 LWC that weighs in at 2.7grams. I verified with separate scales to be sure. Thickness seems to be normal and its not magnetic, am I missing something. Thanks for your input.   |

 That's strange. I would expect to see weakness on the rims from being underweight, but I don't see any of that. A Rolled Thin Planchet would show weakness on the areas of the coin, but there's no weakness, so I don't really know.  Errers and Varietys.

What is the diameter? Do you have pics of the edge?

Here you go, the one in the middle is matched up with a couple of the same year and mint. I did bust out my micrometer and measured the diameter of all coins at 18.92mm, however the thickness differed, the 2.7gram coin measured in at 1.26mm while the others both came in at 3.1grams with a thickness of 1.38mm.   |

That's a good one; I'm furly stumped.. Hopefully one of the experts will weigh in soon.. Swamp EDIT: I will say the material composition looks somewhat different from the other two though..? Edited by da Swampster

Maybe wrong, but if I take the low end of tolerance for a 3.11 gram cent, which is - .13 grams = 2.98 grams and subtract this coins weight 2.7 grams (one decimal) I estimate a difference of .28 grams under weight. So yes rolled thin or light weight, but not by much.
The mints specs for thickness is 1.52mm, but as seen thickness after strike is known to very on coins of normal weight.
Coin has circulated and toned nicely and maybe hiding weakness a bit. To me the bust shows a slight bit on the coats lapel and tie area. Thanks, Doug.

As a matter of fact, I kinda noticed this earlier, and following another look just now I'd say all the highest (lowest?) device areas are somewhat soft.. I didn't really notice that at first when looking only at the lead individual photo of the coin.. But looking at it between the other two in comparison its strike doesn't appear to be as crisp, nor does the rim look to be completely fully formed.. Swamp |

Looks like a slightly rolled thin planchet. Tolerance would let you get down to 2.89 grams so you are about .15 grams light. Technically an error but not really significant enough to command a premium. Find one about .4 grams out of tolerance (about 3 times further out than this one) and you may have some value.

2.89 grams Conder101, my calculator does not compute. Should I be factoring in a curve or variance to get this low end result? Thanks, Doug. Edited by Halo1st

Easy enough to understand flipping the .98 -- .89, but to then blow that incorrect weight's subtraction by typing .15 rather than .19..? I recommend more sugar with breakfast..  Swamp |

The 2.89 was a typo, but the .15 was intentional (but worked from the 2.89 figure) and it made allowances/assumptions thatthe scales rounded the second decimal place and the 2.7 reading could be as high as 2.74.
In any case the final conclusion is the same, slightly underweight but not significant enough to be worth a premium.
