The involvement of ‘civilian’ enthusiasts in the archaeological work in Jász-Nagykun-Szolnok County started in 2015 as a response to an increasingly growing public interest: more and more people, including amateurs devoted to the research of the past, enquired about the possibilities of participating in projects (primarily metal detector surveys) organised by the museum. The almost whole decade of joint work yielded many important results, the presentation of which would exceed the frame of this paper; thus, Celtic enamel brooches, a type of finds considered rare earlier, were chosen to be its focus. Metal detector surveys have yielded altogether 17 specimens of this type so far; the GPS coordinates of their findspots have also been recorded. Ten of these have already been published in previous studies (F. Kovács 2020; 2021), but seven more have been added to our collection since the last overview. This unexpected abundance may contribute to improving our understanding of the Late Iron Age connection network of the Middle Tisza Region and to assessing this find type correctly.
