To be clear, there are two and only two original publications of the
Pozzi collection.
First the Naville
auction catalogue of 1921, reprinted by J.
Schulman in 1966, reprinted again as
part of the 1991 set: 3334 coins, all illustrated on 101 plates.
Second, Boutin's publication of the European half of the
collection of 1979, which was reprinted to form the second half of the 1991 set. This publication includes the 2085 European coins in the
collection that were offered in the sale
catalogue, plus over 2500 more that were omitted from the sale. Total 4630 pieces, all illustrated on 202 plates.
How was
Boutin able to publish these extra coins sixty years after the
collection had been dispersed? Well, at the time he was murdered in 1918,
Pozzi was planning to publish
his collection, and
had entrusted the job to A. Dieudonné of the
Paris coin cabinet. Dieudonné
had composed all of the plates and most of the descriptions of the European
part of the
collection, when Pozzi's death ended the project. A copy of these original plates and the descriptions fell into Boutin's
hands, and he decided to publish them, updating the descriptions with modern references and, based on the images, adding the descriptions that were lacking.
