Analysed coins

Coin catalogue section:	Aphrodisias
Coin corpus dataset:	Aphrodisias, Obols

The number of analysed coins recorded in the corpus as of 2 June 2025 is presented in Table 1 (for coin AP2001, it is not possible to determine whether it is variant 2a or 2b).

Type	Count
2–	1
2a	1
2b	18
Total	20

Die analysis

Identifying the dies of these obols is particularly difficult because of their state of preservation, the quality of the strikes, and the low resolution of some photographs. Consequently, the overview of obverse dies in Table 2 should not be regarded as definitive. The identification of reverse dies is even less reliable, and they are therefore omitted from Table 2; the identity of the reverse dies is certain in only a few cases, such as specimens 8 and 13 of variant 2b.

Table 2: Overview of the obverse dies used to strike individual coins

Estimates of the sample coverage (the number of coins in the original population struck by dies represented in the sample, divided by the total number of coins struck by all dies) and of the original number of dies are given for completeness in Table 3.1 The coverage value of 0.850 is relatively high. The estimated number of original dies is approximately 12, while the observed number of dies is close to the lower end of the 95% confidence interval (7 vs 7.4). However, because the number of coins analysed is small and, as mentioned above, the identification of the dies is not completely certain, these values should be interpreted with considerable caution. Die frequencies—that is, the numbers of dies observed once, twice, and so on—are shown in Figure 1.

number of analysed coins:	20
number of observed dies:	7
mean number of coins per observed die:	2.857
coverage and its 95% confidence interval:	0.850
	0.594 – 1
original number of dies and its 95% confidence interval:	11.8
	7.4 – 18.9
