Thanks to Nirjhar Mukhopadhyay for this brilliant insight, identifying a Rojdi potsherd with an Indus Script inscription. The hieroglyph used on the potsherd is used as Ujjaini symbol on thousands of ancient mint coins from Ujjain and Eran. Clearly, the hieroglyph signifies the wealth of metalwork in mints. See:
'Ujjain', 'nandipāda', 'śrīvatsa' ancient coin symbols are Indus Script metalwork hypertexts https://tinyurl.com/yaljqnhb https://www.facebook.com/srini.kalyanaraman/posts/10156412261649625
