Newman Portal Search Hints

Newman Portal searches from the home page are exact text only. If you enter multiple words, it will search for that entire phrase.

If you wish to search for multiple terms all one page, but not in exact order, use the search form at https://nnp.wustl.edu/library/powersearchform. For example, if you wish to locate pages containing the words "Washington," "medal," "birth," and "centennial," enter the search:

ItemContent:Washington AND ItemContent:medal AND ItemContent:birth AND ItemContent:centennial

You can also use Google to search the Newman Portal site. From Google, enter, for example:

"washington medals" site:nnp.wustl.edu

Finally, you can search the Newman Portal document repository directly (https://archive.org/details/newmannumismatic), which, in some cases, will deliver additional results. On this page, check the box "Select text contents" before searching.

For additional assistance, please email us at NNPCurator@wustl.edu.

FUN Convention Presentation Videos on Newman Portal

Courtesy of Steve Martin, Florida United Numismatists (FUN) board member, NNP has added videos from the educational program presentations delivered at the recent January convention. Sessions from the January event include Biana Bart speaking on paper money errors, Bill Jones speaking on U.S. half eagles, David Harper with his ever-popular “numismatic predictions” for the coming year, and others. This year’s FUN convention drew attendance that seemingly attracted the entire U.S. collector base, but, for those unable to attend, these videos are now available.

Newman Portal Adds American Tax Token Society Newsletters

Courtesy of John Ostendorf, NNP has added the American Tax Token Society (ATTS) Newsletters for the years 2011-2025, completing a 50+ year run of the publication that began in 1971. The ATTS concluded its operation at the end of 2025, and the club leaves an extensive legacy of related research. 

For those not familiar, tax tokens represent a short-lived fiscal convenience created to handle fractional sales taxes that arose when states and municipalities imposed rates like 1%, 2%, or 3% on low-priced goods. States authorized inexpensive metal or fiber tokens, typically valued at 1 mill (one-tenth of a cent), to make exact change possible. Retailers used these tokens to collect the precise tax due, then returned them in bulk to state tax authorities or wholesalers for redemption. Their use peaked in the late 1940s and early 1950s, and faded as prices rose, rounding rules were adopted, and tax rates were adjusted to avoid fractions. Today, tax tokens hearken to an era when a penny remained substantial enough that splitting it into further parts actually made sense (pardon the pun).
