ACSEARCH.INFO Ancient Coin Search Engine. A database created by Simon Wieland, Lars Rutten and Markus Beyeler.
ANCIENTS INFO Coin gallery, articles and discussion board. A very extensive resource, especially great for experienced collectors.
BEAST COINS Many information for experienced collectors and also for novices. The subpage "Not in RIC" was the first inspiration for my project.
CLASSICAL NUMISMATIC GROUP Invaluable "Research" section. A model for other numismatic firms.
CONSTANTINE THE GREAT COINS Great page created by Victor Clark. All you need to know about bronze coinage of one of the most influential Roman emperors.
DIRTY OLD COINS Extensive and easy to use catalogue of Roman coins based on RIC. With searchable legend database.
FORVM ANCIENT COINS Tools for identifying coins, articles and excellent discussion board without which creating this page would be impossible.
HELVETICA'S IDENTIFICATION HELP PAGE Created by Dane Kurth (Helvetica). If you can't afford RIC, you can use Helvetica's spreadsheets instead. Great tool which costs "a hell of a lot of work to do".
NUMISOLOGY Very informative and beautifully designed site devoted to the Tetrarchy period. Extra: how to build a coin cabinet! Created by Robert Bernobich.
WILDWINDS The biggest catalogue of Roman coins on the Web created by the late Dave Surber (now administrated by Helvetica). RIC numbers, inscription search and many more.
