The numbers of analysed coins are given in Table 1. Coins whose weight is unknown or unreliable, or that are excessively corroded or damaged, are excluded from the analysis.

Table 2: Descriptive statistics of coin types

Figure 2 presents relative frequency histograms of the two types; the bars represent the relative frequencies of observations ranging from 3.20 to 3.50 g in increments of 0.10 g. Cumulative distributions are shown in Figure 3. The Kolmogorov-Smirnov test does not reject the hypothesis that the weight distributions of these two types are equal (p-value of 0.986).

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. Above the upper quartile, a distance of 1.5 times the IQR is measured, and a whisker is drawn up to the largest observed data point in the dataset that falls within this distance. Similarly, below the lower quartile, a distance of 1.5 times the IQR is measured, and a whisker is drawn down to the smallest observed data point in the dataset that falls within this distance. Observations beyond the whisker length are marked as outliers and are represented by small red circles.
