Weren’t the bills marked and none have been used or spent? Just my recollection.
Government cover story.
I don’t know if they were marked. I believe some of the money was found along the banks of the Columbia River some years back around Vancouver.
Several bills were found a few years back. One guy got water samples off the bills and has been running up and down each creek and tributary in the area taking samples in search of the sample with a matching “fingerprint.” Seems like a lot of work for $200k.
The bills were not marked. They were photographed. The serial numbers were circulated and eventually published. But cross-checking $20 bills against a comprehensive list would have been remarkably tedious and essentially pointless... there was no reward for finding any of the bills and a found bill wouldn’t have yielded much information in the end...
