British Numismatic Society

Promoting the study of coins, medals, tokens and banknotes





The concept behind this new database is to be able to search for hoards of interest, either within a specified area, or within a specified time range for either deposition date or discovery date. Relevant hoards will then be available in a PDF report, which contains relevant references for your further research.  Where references are available online then clickable links will be provided in the Hoards Report.

Click anywhere on the MCHBI Home Page map to get started, and use your browser's back button at any time to leave the mapping module.

The following explains the functions of the various buttons located around the map:


Click on A, or B, for an explanation of side icons.    C marks the position of the MAIN MENU tab, which is detailed below.

Tip: When a user may wish to use polygons.




See below for details of the four main tabs:



Settings v2

The settings menu is self-explantory.  The illustration shows the default settings which are selected whenever the application is started.  Any changes to these defaults are lost when a user closes the website.  To save settings use the filter settings button (3rd icon at top right).



Sliders v2


A user can select hoards of interest by moving the slider end points. In the example, above hoards are selected whose minimum deposition date (tpq) is between AD 805 and AD 960, having a minimum of 25 coins but no more than 190, and which were discovered from 1901 onwards. In this case 16 hoards were located in the database which meet these criteria. These hoards can be viewed on the map, and the user can download a report (2nd icon at top right).

Working with the hoards displayed on the map.


Simple Search

Here, in Simple Search, one can search hoard data or reference data.  For an example of when to use quotation marks click here


Advanced Search

The above shows an example where the user has selected hoards containing 10 or more coins and issued by one or more Plantaganet rulers. The Advanced Search feature is very flexible, and can be used to interrogate the database for almost any set of conditions imaginable.

Note that both the Simple and Advanced search methods can be used in combination with the "sliders" - i.e. a user may select hoards from a number of coin issuers in the advanced search, and then go to the "sliders"  to further restrict the hoard selection.  This can sometimes be quicker as the hoards update in real time as the slider bars are adjusted.  However use of two search methods at once is not a necessity as all searches can easily be accomplished with Advanced Search once a user becomes familiar with it.
