Tacc Pillar of the Community United States 3535 Posts	Posted 12/24/2023 11:12 am weight of the coin would be the best test for a 40% silver 1971-D as stated below. Edited by Tacc 12/24/2023 12:06 pm Report this Post to the Staff
Brandmeister Pillar of the Community United States 6492 Posts	Posted 12/24/2023 11:29 am The weight is a reliable indicator of 40% silver vs. cupronickel clad. 11.5g for silver clad, 11.34g for cupronickel clad. Those might be roller lines. What does the reverse look like? Roller lines are often on both sides, in the exact same direction. Report this Post to the Staff

Tacc Pillar of the Community United States 3535 Posts	Posted 12/24/2023 12:11 pm Roller lines would not indicate the composition of the coin. Report this Post to the Staff
Brandmeister Pillar of the Community United States 6492 Posts	Posted 12/24/2023 12:29 pm To the best of my knowledge: The Philadelphia and Denver Mint stopped making 40% silver Kennedy half dollars in 1970. The only 40% silver Kennedy coins minted after that point were special proof and business strike coins from the San Francisco mint (which also made CN clad proof coins as well). A 1971-D half dollar is 99.9999% likely to be a normal clad cupronickel coin. Denver produced millions of them. What Tacc said is correct. Any coin can exhibit roller lines, regardless of composition. All it means is that the rollers that stretched the coin metal to the correct thickness were dirty or worn, and they left grooves in the metal. Report this Post to the Staff

Brandmeister Pillar of the Community United States 6492 Posts	Posted 12/24/2023 1:00 pm If you ever run across one in person, the edge is a good start, and then the tissue test: https://www.coincommunity.com/colle...sue-test.asp 40% silver halves reflect differently through a single ply of tissue than cupronickel clad coins.

Dearborn Moderator United States 95437 Posts	Posted 12/24/2023 6:17 pm yes, the lines you see are roller lines - from when the sheet of material was flattened out. Collecting since 1972.
