Found this thread whilst perusing Twitter, and thought you all might find it interesting... https://twitter.com/ancient_tokens/status/1159120806091378688?s=21
I had a lot of pleasure following some other threads of the (numismatic) participants in that Twitter discussion, thanks for the link.
I am actually very surprised this is considered new. The spintriae and the numerical tokens bear obvious similarity and I assumed that a die study had already validated the connection.
