|Coin catalogue section:||Holmoi|
|Coin corpus datasets:||Holmoi, Group 1, Holmoi, Group 2|
|Remark:||The third staters are represented by a single specimen in Group 1 (Type 1.2) weighing 2.96 g. Therefore, only obols, hemiobols and bronze coins are analysed on this page.|
Obols and hemiobols
Table 1 provides the descriptive statistics of individual types (Std. dev. denotes the standard deviation and IQR the interquartile range). Type 1.3 is represented by a single specimen weighing 0.68 g.

Box plots1 of individual coin types are presented in Figure 1. Figure 2 presents the relative frequency histograms. The bars represent the relative frequencies from 0.25 to 0.85 g in increments of 0.05 g and the weight of the only known obol of Type 1.3 is represented by the purple circle on the horizontal axis. The cumulative distributions excluding this single representative of Type 1.3 are shown in Fig. 3.

Descriptive statistics of bronze units (Type 2.5) and half units (Type 2.6) are presented in Table 2. Type 2.6 is represented by a single specimen weighing 0.77 g. Figures 4–6 present the box plots of both types, relative frequency histogram of Type 2.5 (the bars represent the relative frequencies of observations ranging from 0.70 to 1.90 g in increments of 0.10 g) and cumulative distribution of Type 2.5, respectively. The weight of the only coin of Type 2.6 is represented by the red circle on the horizontal axis in Figures 5 and 6.

1The bottom and top of each box are the 25th and 75th percentiles of the dataset, respectively (the lower and upper quartiles). Thus, the height of the box corresponds to the interquartile range (IQR). The red line inside the box indicates the median. Whiskers (the dashed lines extending above and below the box) indicate variability outside the upper and lower quartiles. From above the upper quartile, a distance of 1.5 times the IQR is measured out and a whisker is drawn up to the largest observed data point from the dataset that falls within this distance. Similarly, a distance of 1.5 times the IQR is measured out below the lower quartile and a whisker is drawn down to the lowest observed data point from the dataset that falls within this distance. Observations beyond the whisker length are marked as outliers and are represented by small red circles.
