The
hoard was found in an official excavation, indeed, however, on a private property. Thus, under
German law, 50 % would belong to the property owners However, the owners decided to donate their share to the public. Thus, the
hoard will stay united and will be shown in Augsburg's
Roman Museum in December and January (I figure before restauration).
Please note, however, that Augsburg's temporary
Roman museum (the former museum was of considerable size in a former Dominican monastery
church) is currently housed in the city's "Zeughaus" with extremely limited space. This - indeed depressing - situation of archeological presentation of Raetia's capital city's discoveries (and there are quite some a amazing things, i.a. a
hoard of 52 beautifully preserved
aurei) has been going on for years, now. At this point, there is not even a plan when and where to re-open the old museum or to create an adequate new one.
