This report concerns a long-term study of a field situated at the southern boundary of Cropwell Butler parish, where exceptional finds have been revealed in the course of metal detecting. The field was examined first in 2005, and subsequently in 2013 and 2016. The most informative of the finds were the Romano-British coins, of which we found 60 over the three periods of study. Some were too worn to identify precisely, but the better preserved examples have been identified and approximately dated. The great majority were from the 4thC AD, towards the end of the Roman occupation, and these were mainly concentrated in the northern half of the field in two sites, one larger area in the north-eastern corner, and a smaller area at the north-western margin. A few earlier coins from the 3rd C AD (mainly so-called barbarous radiates) were also found. Two silver coins were found, a denarius of Caracalla, 201-206AD and a base silver issue of Claudius II, 268-270Ad, the remainder all being low denomination copper alloy/bronze. Some of the coins were so worn that they were unidentifiable, but had the characteristic size and thinness of 4thC AD coins. The identifiable 4thC coins were mainly of two types. The first examined area close to the drainage ditch and pond showed a majority of Magnentius issue bronze coins, dateable to between 350 and 353 AD, whereas the area in the north-west corner of the field close to the road showed a predominance of coins from the House of Constantine, covering a time span of 317 to 380 AD, although most were approximately 330-360AD. The other Roman artefacts found were comparatively few, and included parts of brooches, suspension mounts, a locking pin and part of a bronze bell. It is interesting that these are earlier than the Romano-British coins, being mostly of 1st-2ndC AD style. The reason for this discrepancy is not apparent. Also found were some sherds of Romano-British pottery, mainly in the same areas as the main concentration of coinage. This was almost entirely grey ware, possibly locally produced, but our team does not have the expertise to identify it further. No Samian-ware fragments were found. Numerous lead artefacts were also discovered, mainly lead weights, musket balls and spindle whorls. It is not certain if any of the weights or spindle whorls were from the Romano-British period.
