The position of the Newman Numismatic Portal at Washington University in St. Louis gives us access to the Federal Depository Library Program (FDLP), a group of over one thousand libraries with the mission to make access to federal documents more accessible to the general public. This includes Mint and Treasury documents as well. The latest addition is a visitor brochure, How to Make a Penny, which was distributed by the Denver Mint in the early 1970s.
The main feature of this publication is a flow chart representing Lincoln cent production from raw metal to struck coin. No doubt discarded by the public in great quantities, the best source of such documents today are programs such as FDLP, and the Newman Portal is grateful to Barbara Hofmann, Washington University Library Technical Specialist for U.S. Government Documents, for bringing it to our attention.
