Figure 2: Relationships between object records held in different UK datasets: a) 'box and whisker' plot showing the percentage overlap between PAS/EMC records and HER records based on evidence from 35 10x10 km squares located across England) (see Cooper and Green 2016, 285, for the location of these squares) (the thick black vertical line shows the median value for each class; the 'box' shows the interquartile range; the horizontal 'whiskers' show the overall distribution of values) and b) chart showing the distribution of key sets of object records (non-metal, metal, coins, hoards and all finds excluding hoards) across different datasets for the Isle of Wight

Figure 6: Comparison of the tempo of Roman coin loss at a national level (PAS mean) and on the Isle of Wight (Isle of Wight mean) using Reece periods (following Walton 2012, 120)

Figure 7: Collated probabilities of PAS find dates from 1500 BC–AD 1086 using fuzzy time-slices, weighted by artefact quantities

Figure 8: Comparison of all PAS coin finds from 1500 BC–AD 1086 (material from hoards and from isolated finds): (a) comparing traditional coin periods and fuzzy time-slices for England; (b) the same for the Isle of Wight; (c) comparing finds from hoards and single coin finds using fuzzy time-slices for the Isle of Wight

Figure 9: Hoards (including materials of all kinds) through time using 20-year fuzzy time-slices, showing: (a) probable number of hoards at a national level (black line; left y-axis); (b) hoards from the Isle of Wight as a percentage of the national figure (shaded columns; right y-axis). Because of the fuzzy approach used, the national level pattern of deposition is a composite weighting and should not be read as the absolute number of hoards within any time-slice, but more as the weighted probable number of hoards

Figure 10: Comparison of temporal patterning in PAS (single) coin and brooch finds for the Isle of Wight using fuzzy time-slices: (a) summed total probabilities multiplied by finds quantity; (b) as (a) but normalised by mean and standard deviation (z-score) for easier visual comparison (positive values are in standard deviations above the mean, negative values below)
