Numismatist and U.S. gold specialist Doug Winters is publishing online a numismatic reference on U.S. gold Coronet $20 double eagle coins that can be updated as new information is uncovered, without collectors having to buy a new copy of a print version.
Winters, of Doug Winters Numismatics in Portland, Ore., is starting first with Type 1 $20 gold double eagles, the Coronet, No Motto gold $20 double eagle series covering the years 1850 to 1866.
The online guide sharing his numismatic research, Type One Liberty Head Double Eagles, is an outgrowth of his 2002 print book, An Insider’s Guide to Collecting Type One Double Eagles. Winters had previously written on New Orleans double eagles in New Orleans Gold Coins: 1839-1909, published in 1992 and revised in 2006.
“After numerous starts and stops, I decided to revise the  book in 2014 but with a twist: instead of publishing it in traditional book form, it is here as a web-based project,” Winter says on the book website. “This was done for a number of reasons. The first is flexibility in updating. With a traditional book, updating it is a major chore. With the new web-based format, it will be easy for me to continually update things like Condition Census, Auction Price Records, certified population figures, hoards, and important new discoveries.
“A web-based double eagle book will have a far greater reach than a traditional published book, and this might serve to bring more new collectors into the series. It will also enable me to have interactive features such as a comments section where collectors can add their input to each issue, and expanded potential to include more high-quality color photographs than in a traditional printed book. The possibilities are endless.”
DoubleEagleBook.com is a non-commercial educational division separate from his commercial website, RareGoldCoins.com business web site.
DoubleEagleBook.com does not contain any coins or other numismatic items for sale, according to Winters. The online reference is intended to provide collectors with as much information as possible so they can make wise buying choices, whether through him or other dealers specializing in U.S. gold coins, Winters said.
Winters says he plans to add on to DoubleEagleBook.com, with segments dedicated to Type II double eagles covering 1866 to 1876, and Type III double eagles from 1877 to 1907.
Type I Coronet double eagles are those that do not bear the motto IN GOD WE TRUST, which was added within the circle of stars above the eagle’s head on the reverse in 1866. Type II coins are With Motto issues that also have the denomination on the reverse presented as TWENTY D. as introduced on inaugural circulation strikes in 1850.
