The 1982 D Small Date Memorial Cent worth $1,260,

The 1982 D Small Date Memorial Cent is only worth one cent unless struck on a copper (bronze) blank that weighs at least 3.0 grams. Only two were found struck on a blank, so they are extremely rare, with the first find selling for $18,000. The 1982 Lincoln Cents are the most confusing date in the Lincoln Cent series because there are 7 different types, 8 different if you include the small date on a bronze blank. And they are as follows: large date and small date, with a mint mark D for the Denver Mint and no mint mark for the Philadelphia Mint and the West Point Mint, and half were struck on zinc plates copper plated which weigh 2.5 grams and the other half on copper board of grams. However, a mistake was made, the small date 1982 D was supposed to be struck on copper plated zinc planchettes which weigh 2.5 grams, but two were found on the copper planchettes which weigh over grams . So how do you know if it’s a small date? One way is to hold them side by side and compare them,
