John Frost Speaks on 20-Cent Pieces

Recently added to Newman Portal is a video of the Liberty Seated Collectors Club (LSCC) Zoom meeting held May 11. Most clubs are seeing increased meeting attendance with virtual formats, and the LSCC is no exception, drawing over fifty attendees to this meeting. With one-click recording, the preservation of this content is simple, and LSCC has elected to share meeting videos externally. This event featured John Frost speaking on 20-cent pieces, all the way from the related legislation to the cataloging and collectability of interesting varieties. Frost, and Lane Brunner, are the authors of the standard work on the series, Double Dimes: The United States Twenty-cent Piece. Their research is freely available on their website, and hardcopies are also offered for sale.

John S. Dye and His Counterfeit Detectors

Recently published on Newman Portal is Patrick Parkinson’s work John S. Dye and His Counterfeit Detectors. This study documents the history of John S. Dye’s counterfeit detectors, a task made difficult by the ephemeral nature of such publications. Because new counterfeits and new genuine bank notes were constantly being circulated, counterfeit detectors quickly became outdated and were discarded, leaving very few surviving copies. This book fills in the gaps, largely through advertisements and articles in digital databases of contemporary newspapers. Parkinson’s work is meticulous and will be welcome by anyone interested in 19th century counterfeit detectors. 

Lianna Spurrier performed book design, graphics, and layout of Parkinson’s work under sponsorship of Newman Portal. The result is an elegant presentation, with the visual appeal matched only by the content. Newman Portal welcomes inquiries by prospective authors in need of the same services, and currently has similar projects in production, which will be announced in due course.
