NNP Site Navigation
[July 8, 2026] Welcome to the new NNP. The site has migrated from a custom ASP.NET application (developed by John Feigenbaum and Greg Bradley) to the Quartex platform, which is used widely by libraries, archives, and museums to organize and present digital assets. The site navigation remains largely identical with a few notable differences:
- The Eric P. Newman Archives have been moved from the general archives and now have a dedicated section. This portion of the site presents Newman's correspondence, research papers, and publications.
- Fixed price lists, previously listed under periodicals, now reside in a separate collection dedicated to dealer price lists.
- Articles, which appeared only in search results on the earlier site, are now directly viewable as a separate collection. This section includes an archive of the weekly E-Sylum in addition to numismatic articles extracted from non-numismatic sources such as the Historical Magazine.
- Alphabetization is now more rigorous with last name placed first in series names. For example, fixed price lists of Q. David Bowers are now titled as Bowers, Q. David Fixed Price Lists.
- Image collections now group together multiple views of the same object. For example, most coins will now have obverse & reverse images grouped together.
- The NNP Encyclopedia function is no longer supported. Pricing data is available at other sites, including https://www.greysheet.com/coin-prices, https://www.pcgs.com/coinfacts, and https://www.ngccoin.com/coin-explorer.
The extensive collections of auction catalogs, periodicals, etc., retain the same structure as on the original site.
