Digitalization and Characterization of Ancient Coins

Digitalization and Characterization of Ancient Coins

 

Digitalization and characterization of the collections of Greek and Roman coins in the various Numismatic Collections at the FAU and providing them in an online database is an important step towards a Virtual Research Environment (VRE), providing input for the Semantic Web reacting to the demand of Open Linked Data.

3D laserscans provide the possibility to study these coins using non-destructive methods in order to trace the craftsmanship of ancient Greek and Roman metalworkers. Virtual sections of these coins provide information which cannot be collected otherwise without completely destroying these precious ancient artefacts.

In addition, a complete image composed by many single BSE (backscattered electron) images reveal possible exsolutions or alloy anomalies.

By mapping these BSE images onto the 3D model of the coin we achieve a unique insight and far more complete picture of these ancient masterpieces from a metallurgical point of view.
