While analysis is fun, data base building is a dull, but necessary investment into future research. This paper (https://www.academia.edu/23738461/Analysis_of_the_metal_of_the_coins_of_Ebusus_and_Northeastern_Spain_3rd_1st_c._B.C.E._?email_work_card=abstract-read-more) develops data for a narrow, range of coins that is so under-studied that Cayón does not cover them in his benchmark catalogue of Spanish coins.
Analysis of the metal of the coins of Ebusus and Northeastern Spain (3rd – 1st c. B.C.E.)

During the late 1980s, X-ray Fluorescence (XRF) spectroscopy played an important role in developing our understanding of the composition of ancient bronze coins in the Iberian Peninsula, but the studies involved addressed only individual mints and issues and did not aim at developing a wider picture. Between 1995 and 1999, Abascal and Ripollès, building on previous work, undertook a series of metallographic analyses, also using XRF spectroscopy, published in four papers . Their goal was to produce an initial databank of information on the composition of coinages minted in the Iberian Peninsula during the Republican period and the early Empire, and map this. This remains the only systematic treatment of this material so far completed, though some further analyses were undertaken by other scholars.
The aim of this paper is to add yet more data to the existing databank of metallographic analysis of Iberian coinages, and present the results of an analysis and comparison of the composition of the bronze coins of the Punic mint of Ebusus and the Iberian mints of NE Spain, during the 3rd-1st c. B.C.E.: 339 coins were analyzed using XRF spectroscopy. In the case of Ebusus, the sample was large enough to make possible a diachronic study of the metal composition during the life of this mint.
