I have a question about whether I may have discovered a Lincoln Memorial Penny (brass cent) that appears to me (with my limited knowledge) to be a Double Struck Through Die Error. On the other hand, this penny may be just a post mint acid or mutilation job. There is no rim on most of the coin and its edge reveals a split planchet around its total circumference. No date can be ascertained; however, on the obverse, the letter D, for the Denver Mint, does appear to be visible albeit higher up than its should be (approximately where the year should have been struck on the coin). This penny weighs in at only 3.00 grams. If anybody has information on whether this is an error Lincoln penny, please give me your feedback. I have included images of the obverse and reverse for your review.
Struck through car tires in the parking lot. Sorry, but that is damage. Welcome to the forum! EDIT: Cents are made of copper, not brass.
Not exactly. IIRC, cents from the early 1960's (I forget the date) to 1982 were made from 95% copper and 5% zinc. Do you know what brass is an alloy of?
True, but they are also traded as copper bullion due to the purity. Our silver coinage, accepted worldwide as bullion, has never been as pure as a copper cent.
So a copper/zinc alloy is bronze and not brass? It's been a while, but as I understood it, once tin was removed in the early 60's, cents were no longer bronze.
Yes, but since it is still 95% copper it would be considered copper rather than brass, which i believe has more then just 5% zinc.
Copper and zinc makes it brass, different proportions and other added metals make it different types of brass.
Brass cents are approximately 95% copper and 5% zinc. Bronze cents are approximately 95% copper, 4% zinc, and 1% tin.
