PELLA is a project of the American Numismatic Society directed by Dr. Peter van Alfen. The web database, based on the Numishare platform, has been developed by Ethan Gruber.

Substantial work in developing PELLA has been carried out by Prof. Andrew Meadows (Oxford University). Cynthia Cheng, Yoorim Choi, Sylvia Czander, Elena Ferrero, Disnarda Pinilla, and Clara Sanchez provided considerable assistance in organizing material within the ANS collection. Alan Roche is responsible for the photographs of ANS coins. At the British Museum, Martin Price, former Curator of Greek coins, was instrumental in cataloguing this material. Amelia Dowler is the British Museum's current curator of this series. Prof. Bernhard Weisser and Dr. Karsten Dahmen have catalogued the material at the Münzkabinett of the Staatliche Museen zu Berlin. At the Bibliothèque Nationale de France (BnF) Caroline Carrier catalogued the Alexander types, while Simon Glenn did the same at the Ashmolean Museum at Oxford.
