No certain provenance pre- 1988. 
But some reported rough find spots…
Just saving for later with this post. I want to think more about these at some point.
Also I don’t believe this last is supposed to be a Zebu or Brahma Bull… Looks too much like a badly drawn elephant esp a mash up of African and Indian features….
I grant you the hump looks vaguely like this a zebu hump but creature on weight has trunk and also domed scull and curved back and NO HORNS.
Frankly I’ve my doubts about its authenticity….
Must thank Eduardo García-Molina on Twitter for bringing these weights to my attention.

“On metrology, there’s been a lot of work by Kushner-Stein and Finkielsztejn on Seleukid weights. I wonder where these fit into F.’s theory (no enshrined in a narrative in this big article by Honigman et al. in a vol. on Antiochos III from a few years ago) of a major reform in the time of Antiochos IV.

Thanks for this! I’m going to add it to the post itself so it doesn’t get overlooked.
[…] I love this coin for so many reasons, but it gets a blog post because I want to revisit these weights I blogged about earlier in light of this reverse iconography. […]
