Plate Coin

Plate coins are illustrated in the plates of published works. Often these will be from die-studies, published collections, or works that are considered standard references but may also include articles in numismatic journals. The attraction to collectors is that their coin can be seen in a publication and the owner can be more confident about their authenticity.

Hoard Coin

Coins which were discovered in a documented hoard. Typically these will be documented in the Coin Hoards series. The attraction to collectors is that they form part of an archaeological discovery and that their authenticity can thus be established by reference to the hoard they were found in.


Coins which were part of a well-known or established collection are 'pedigreed' if their provenance can be established e.g. via auction records, coin flip inserts, or other information. Often it can be established that these coins were in collections decades (or longer) earlier. Their attraction to collectors are numerous but principally they are considered less likely to be modern forgeries given their provenance can be dated to periods prior to many of the modern counterfeits found today.

Ancient Counterfeits

Coins have been counterfeited for probably as long as coinage itself. Ancient counterfeits range in quality, from closely resembling the official issues, to crude attempts to do so. In many cases, these counterfeits use a base metal core, which is then plated, or pressed with a precious metal. Such coins are known as fourrees.
