SCRelicHunter New Member United States 18 Posts	Posted 11/19/2025 10:28 pm Hey folks, I have a worn 1937 copper penny that weighs 2.925 grams and a similarly worn 1944 copper penny that weighs 3.335 grams, with both measuring 18.98 mm in diameter. Considering that a normal good condition 1937 penny should weigh around 3.11 grams and a 1944 penny about 3.11 grams as well (I also understand that the 1937 is in the correct weight range for it's condition), can anyone help identify the possible reasons for the weight of the 1944 penny? Thanks in advance for any input! Report this Post to the Staff

Dearborn Moderator United States 95403 Posts	Posted 11/20/2025 07:22 am yes, Marve hot the spot here. Your 1937 is light due to the weal and loss on metal over time (could also have been slightly 'under weight' from the start due to a rolled thin stock.) and your 1944 was rolled out on extra thick stock - adding a bit of weight. And here I thought your question was going to be about the differences in the color of the coins. Collecting since 1972. Learning from then on "Tell me and I forget. Teach me and I remember.

nickelsearcher Moderator United States 15402 Posts	Posted 11/20/2025 08:19 am A related question - In 1944 and 1945 the mint recycled used WWII shell cartridges to source the 'copper' for the cents. Did this result as well in an alloy change that altered the expected weight of those coins? Take a look at my other hobby ... http://www.jk-dk.art Report this Post to the Staff

Many recent posts with early wheat cents seem to show evidence of poor quality control back then. I believe a thin rolled stock would have been easily ignored.

SCRelicHunter New Member United States 18 Posts	Posted 11/20/2025 2:12 pm Excellent information everyone, thanks! The link will be very helpful! Quick question though: Should there be a row added or footnote for thick rolled stock as it seems the 1944 coin if in good or excellent condition would be far above the maximum tolerance? Thanks again! Report this Post to the Staff

Not really. The mint isn't going to reject rolled stock if it is slightly over or under tolerance. That just wouldn't be cost effective for them. Especially back in the 40's and 50's when the QC wasn't very strict like jbuck stated.
