of Bactrian Kingdom around the middle nineteenth century hold all of these Kings to be contemporaneous co-rulers. Among the rare dissenting voices was Alfred von Sallet who asserted that these "ancestor coins" were struck for the purpose of commemoration and rejected that these rulers were contemporary, based on the design of coins. In 1880, a coin of the same kind struck by Agathocles but "commemorating" Alexander, Son of Philip was published by Percy Garnder of British Museum. That it was impossible for Agathocles to be a sub-king of someone who had ruled about two hundred years earlier, Droysen's explanation was summarily rejected in favor of Sallet. Gardner proposed that these coins were struck to increase his public on the eve of an (eventually successful) challenge by Eucratides I. In the early-mid 1900, Hugh Rawinson and William Tarn would extrapolate Gardner's ideas to further their visions of a grand Hellenistic past where Agathocles had faked his pedigree and Eucratides I was carrying out the orders of Antiochus IV to reestablish the Seleucid control. Other scholars generally avoided giving too much significance to these "ancestor coins". More varieties of these coins would be discovered later. These mention Diodotus II, Demetrius II and Demetrius. In the last few decades, such coins have been discovered in more numbers but the accuracy of these finds remain plagued by the fact that these did not came from controlled excavations but auction networks. They were evaluated by scholars only after they have traveled continents and passed through multiple hands. It has been since accepted that these coins indeed represented Agathocles' predecessors. The precise context of minting and significance is still not clear. Religious coinage Agathocles was unique in issuing bilingual coinage. Meant for local circulation in Gandhara, they were typically of smaller denominations, square or rectangular in shape, and minted in bronze or silver. The obverse had his portrait labelled in Greek while the reverse had imagery from the Buddhist as well as Hindu pantheon alongside inscriptions in Brahmi/Kharosthi. Monolingual coinage (in Kharosthi) of similar kinds have been discovered. These finds have led scholars to conclude that Agathocles favored socio-religious tolerance. Osmund Bopearachchi hold him to have inaugurated the first Indo-Greek era; others have been skeptic. Buddhist Buddhist symbols such as the stupa and the "tree in railing" have been located in his coins. These coins sometimes use Brahmi, and sometimes Kharoshthi, whereas later Indo-Greek kings only
