Collection Map

This page provides an easy tool for visualising the geographic extent of the coins from my collection by grouping them by the cities they were likely minted at. While the coins are grouped by their mints, the purpose of this page is still to provide a coin-level tool, not one that summarises data at the mint-level. Thus, the filter tab in the map allows you to filter on attributes of coins in my collection, not attributes of mints as in my Coins of Alexander Map.

The gallery below the map shows a photo and summary of each coin in my collection that fits the filter criteria applied. Thus, if you filter using the attribute “Denomination” and select the value “Tetradrachm”, you will only see coins in my collection that are Tetradrachms. If you have the “Show only Selected Mint/Coin” toggle enabled and then click on a specific mint from the side-panel, or if you click on a mint on the map itself, the gallery will further update to only show coins that are tetradrachms and that belong to the mint you have selected. Clicking on a coin within the selected mint will further refine the gallery to only show that specific coin.

The map filters can be accessed by clicking on the “Filters” tab from the panel to the left of the map. There are two types of filters: dropdowns and inputs. The dropdown filters allow you to select one or more values at a time. Each value in a given dropdown filter are combined using an “OR” operator. For example, if you select “Abydus” and “Babylon” from the Mint filter, the map will be filtered to show both the Abydus and Babylon mint. However, if you then set the Region filter to “Egypt”, there would be no results as two different dropdown filters combine together with an “AND” operator. Since neither Abydus or Babylon are located in Egypt, no mints would match the filters and the map would be empty.

The input filters can only accept one value per input field but each filter has two input fields, one to set the minimum value and one to set the maximum value. You can, however, just set one, you don’t need to set both. For example, to view all coins with an “earliest” mint date after 323 BC, you can set the first input field of Earliest Mint Date to 322 and not set the second input field (the max value). If you want to see all coins that have an Earliest Mint Date of exactly 322 BC, set both input fields to 322.

To demonstrate how the logic would work using the examples above, the logic would read as follows:

Mint="Abydus OR Babylon" AND Region="Egypt" AND Earliest Mint Date ="from 322 to []"

This would translate as: the mint is equal to Abydus or Babylon, and is in the region Egypt, and the coin was not minted until 322 BC or later. Currently it is not possible to have “OR” conditions between filters, such as Mint=”Abydus” OR Region=”Egypt”.
