The "Grand document" by François de Callataÿ and Guy Meyer brings together evidence primarily about numismatic correspondence that was exchanged before 1800 and is part of the project "Fontes Inediti Numismaticae Antiquae (FINA)".
The FINA Wiki is an online version of the "Grand document" that makes its content available on the Internet, thereby inviting researchers to collaboratively collect further resources.
