### Basic statistics

Box plots1 and basic descriptive statistics are presented in Figure 1 and Table 1, respectively. Single representatives of Types 1a and 2 are shown by red horizontal lines in Figure 1. A total of 15 specimens of Type 1 are analyzed, as the weight of coins nos. 17–18 are not known. Coin no. 2 is distinguished from other coins by its very low weight of 9.84 g. According to the photograph in the auction catalogue, it appears to be well preserved and without signs of metal degradation.

**Table 1:** Descriptive statistics of Type 1b

Figure 2 presents the relative frequency histogram. The bars represent the relative frequencies of Type 1b coins ranging from 9.80 to 11.00 g in increments of 0.10 g. The isolated bar on the left corresponds to the outlier mentioned above (coin no. 2). Weights of the only known specimens of Types 1a and 2 is represented by the blue and red circles on the horizontal axis, respectively.

### Comparison with Kelenderis staters

The following Figures 3, 4 and 5 show the comparison of Type 1 (i.e. both variants 1a and 1b) with Groups 1, 2 and 3a of Kelenderis staters. Comparison with Groups 3b and 3c is unnecessary as they are characterized by significantly lower coin weights. For definitions of Groups 3a, 3b and 3c, see section Weight Analyses / Kelenderis, staters.

This comparison suggests that the weight distribution of the Pseudo-Kelenderis coins of Type 1 can be roughly classified between Groups 2 and 3a of the Kelenderis staters. The time of their minting could thus be dated to the turn of the 5th and 4th centuries BC. However, this is only a speculative assumption for now.

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.
