This series of data captures a US one cent coin with two different systems, at 3 resolutions:
- PennyBack-LincolnAndPillars, this dataset, measured with a Zygo NewView 8300 at 2.75x.
- Penny-All shows the entire back of the coin, measured with a Keyence VR-3100 at 12x.
- PennyBack-Lincoln measured with a Zygo NewView 8300 at 10x.
