Publisher's Synopsis
The guide is an accurate measurement of all Lincoln cent dates and profiles. When searching for varieties, error coins, and anomalies, this guide contains all the collecting measurements to compare one coin to another. The measurement of coin profiles, the date, the coin's diameter, and the coin's width is critical for discovering some potential error coins, otherwise passed up by the novice collector. The tools used to validate coin variations are a microscope, a caliper, a centimeter scale, a gram weight scale, overlay software, and a set of brilliant uncirculated coins.
