I was referring to the condition of the bills...  they are consistent with sand abrasion and tidal/water action over some time.

I'll throw something out there that I ran across recently..

I was watching video interview with the Treasury Department about mutilated currency and its "recovery".

They showed termite damage and it looks very similar to many of the Cooper bills, those holes look exactly like termite damage.

That got me thinking, what if the money was stashed in an attic, garage or similar environment for years and termites got to it in its original bundle form, leaving the rubber bands preserved and intact but eating away the money.

The money discovered severely damaged couldn't be used or sent to Treasury as damaged for replacement. It was rendered useless and discarded ending up on TBAR enduring some further erosion and chard dispersion.

I found that the Portland area does have invasive house termites and they love to eat paper..

This is a bill eaten by termites, but a tight bundle may produce more damage at the edges..

Circular holes are indicative of termite damage.

Why were the Ingram’s on the beach in February?  Why would they be on Any beach in February in the Pacific Northwest.   And the boy just happened to be digging in that one spot?  That’s some coincidence.  Lol!  Has anyone checked the Ingram’s phone records from the Fall of ‘71?

You know, you're right. I'm just wasting my time here. After all, the case was solved a decade ago. It says so right here:

One of the agents excavating described how when they were raking they uncovered what at first appeared as a 'piece of driftwood' - but on examination it turned out to be a soft 'fist sized' clump of rotted money. This has been referenced before. As here:

"One article states that the money "looked like a piece of driftwood" - and had young Ingram offering it up to Dad as firewood before they realized what it was. Another article addresses further searches in the area found fragments and an FBI agent says he found a "fist-size clump of wadded up $20 bills" that appeared like driftwood." (Smokin99 DZ)

Lots of people were seeing lots of driftwoods. Little driftwoods and bigger driftwoods. All planted like seeds on the beach. Perhaps directed by the Cooper Cartel with Farmer's Almanac in hand.
