Analyzed coins
| Coin catalogue section: | Pseudo-Kelenderis Mints |
| Coin corpus dataset: | Pseudo-Kelenderis Mints |
The numbers of analysed coins are given in Table 1. Those coins that are listed in the coin corpus without weights or that are marked there as too corroded or damaged are excluded from the analysis.

Analysis
Box plots1 and basic descriptive statistics of Types 1 and 2 are presented in Figure 1 and Table 2, respectively. Coin no. 2 (Numismatik Naumann, Auction 55, Lot 359) is distinguished from other coins by its very low weight of 9.84 g. However, according to the photograph in the auction catalogue, it appears to be well preserved and without signs of metal degradation and was therefore not excluded from the weight analysis.

Table 2: Descriptive statistics of Type 1
Figure 2 presents the relative frequency histogram of Type 1. The bars represent the relative frequencies from 9.80 to 11.00 g in increments of 0.10 g and the weight of the only known specimen of Type 2 is represented by the red circle on the horizontal axis. The cumulative distribution of Type 1 is shown in Figure 3 (the weight of the single specimen of Type 2 is again represented by the red circle on the horizontal axis).

Figure 2: Cumulative distribution
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.
