In reference to the question you asked about the US Dept of Teasury Customs service badge. It appears to be more like a lapel pin or a novelty item. The credential wallet that it is in is much too big for this pin/badge. It does say that it is for a special agent. There were no credentials in the wallet.
They were still looking at this at the FBI in summer 2025.
