On his [[Sasanian coinage|coinage]], Bahram IV is portrayed wearing a crown with wings—a reference to Verethragna. The wings are attached to a [[mural crown]], which was a symbol of the supreme god in Zoroastrianism, [[Ahura Mazda]].{{sfn|Schindel|2013|p=830}} Bahram IV was the first Sasanian monarch to combine two religious components on his crown. Afterwards such crowns became a common feature among the Sasanians.{{sfn|Schindel|2013|pp=830–831}} It was also under him that the use of mint signatures became regular.{{sfn|Schindel|2013|p=818}} The regularization of mint signatures allows the origin of coins to be more easily identified. Under Bahram IV, the eastern province of [[Abarshahr]] produced its largest proportion of coinage (19%) throughout Sasanian history.{{sfn|Howard-Johnston|2014|pp=164–165}} The large production of coins in the region was to meet the expenditure needed to maintain the large number of troops stationed there.{{sfn|Howard-Johnston|2014|p=164}}

Like Shapur II, Ardashir II and Shapur III, Bahram IV also minted [[Sasanian coinage of Sindh|unique gold coins]] in the [[India]]n region of [[Sindh]], which may have corresponded to the Sasanian province of [[Hind (Sasanian province)|Hind]].{{sfn|Schindel|2016|p=127}} Under Bahram IV, mints were established in the cities of [[Gundeshapur]] and [[Susa]] in [[Khuzistan (Sasanian province)|Khuzistan]].{{sfn|Jalalipour|2015|pp=12–13}} A mint was also established in the northwestern province of [[Adurbadagan]] to support the construction of the [[Caspian Gates]] to protect the [[Caucasus]] border against Hunnic incursions.{{sfn|Bonner|2020|p=95}}{{sfn|Howard-Johnston|2014|p=164}}
