okay.
the fbi memo is 34 pages of serials. 33 pages of 600 serials. 1 page of 98 serials. front page from Hoover, last page of fbi offices and phone numbers.

tosaw may have chopped it up differently.

I guess I'm not sure what we're disagreeing about.
You don't have a full list, and the list you have is of unknown accuracy.

I think you're just agreeing it's a lot of work.
Me, I'm just bragging before I'm done.
calling the eight-ball pocket so to speak.
I will have the best list, and I'll make it accessible on Google Drive for all.

The only list I have is the list from the Tosaw book I bought.  I counted and it is 2 short of 10,000.  I've been under the assumption that this is the only list out there and the list from the papers is from the book.  I'll check back later and see what you've found.  It's hard to keep track of all the posts across platforms.  It sounds like the FBI list and the list in the papers may not be the same??  Or that list is wrong?  Or that the FBI may not even know for sure of the serial numbers they gave Cooper, or the exact serial numbers of the $6000 or so that was found on Tina Bar.

It would have been a tragedy if someone found a Cooper $20 and went to the list and it was not on there.

Good luck with everything.  I still think some of the money went into circulation.  I certainly don't think it is still sitting in the woods, or is at the bottom of the river or the ocean.

another that looks to me like a fbi typo


L00 832 10C* 69
Should be  who knows what? 0-9 is legal there, not C
maybe
L00 832 100* 69

it really seems to me like a typo, not a poorly printed 0 ?? The other typo was a C also. That was more obviously a typo, because if it as 0, it would have meant consecutive non-star serials which is unlikely (I should try to calculate that probably given the number of bills per series year, assuming bank had random distribution mostly from L San Francisco Reserve...but it's a low probability, I think.)

middle serial in the screenshot.
I'm going to use 0. here's the full location info (page/row/group)
L00832100* 1969  167 15 C

 EDIT: I checked check six. He used 0.

good summary of info, georger.

good summary of info, georger.

could be important - been mulling this over for a long time - if it could ever be proved the money was in two distinct places during its history (cold and warm) that would change the whole money narrative. One can only follow the evidence...

How cold and how warm?

How cold and how warm?

also: it seemed like georger was suggesting that the warm happened before the cold.
you could imagine a cold then hot sequence (water than hot on beach)

but georger: are you pondering a hot then cold sequence (maybe followed by a hot sequence (beach) that didn't change things because already crystalline?)

If bands reach the gooey then crystalline stage, that's it. Once the sulfur bonds come apart that's it. Once crystals form they simply dry out and harden. No reversal possible.

The whole process is temperature and (uv, ozone) exposure driven. Im guessing within the first year? Tom might say first several months? But it could have taken two years. This is all speculation based on the Ingrams description of 'picking off band pieces that were stuck to bills'. If we could examine those band fragments in a lab we would know as fast as we could get a sample under a microscope ... if we had a piece of band stuck to a piece of money fiber that would be decisive. Its asking for a miracle!

The story about the brother-in-law picking off pieces of band is official - part of the FBI official interview of Pat and Harold. 'they showed it to INGRAMs brother-in-law, who took the rest of the rubber bands off and was going to dry out the money and try to reclaim it.' The brother-in-law worked on the money on their kitchen table. 

Found a case where the check six site has an incorrect serial number. Says it matches when it shouldn't.

L19362280A 1969

you can plug it in here, and it will say you have a match

It's a reasonable error, because  when you look at the serial number, it really looks like 362 in the 2nd group..i.e.
L19 362 280A

But when you look at the context, and know that the list is sorted, you know that it's really a 382 with the top part of the 8 not well printed. Knowing that the fbi list was sorted is critical for context to aid verification.

The correct serial is
L19 382 280A 
or
L19382280A 1969
which check six says is not a match

I've been reading some collector books on bills.
Fascinating amount of detail.
Engaging the collector community will be interesting once I have a list of star notes.

 


here are all the relevant printings of $20 bill and series year.
The 1934/1950/1963/1969 seems odd, until you see that those were the years that had printing or $20 bills.
none in intervening years.

Was thinking about paper. I believe the paper used as not changed since those years.

They did some experimental runs of different paper (like the so-called Natick paper) for $1 bills in 1981
Still reading but I think $20 paper has always been consistent.

U.S. currency is printed on special paper made by Crane Paper Company. Unlike traditional paper made of wood pulp, the paper used for currency is made of 75 percent cotton and 25 percent linen.

Idea: I wonder if the cotton/linen mixture decays in a non-uniform manner. Maybe interesting in terms of understanding the holes in the cooper money found.

Why not more mold?

Bruce, maybe you could interview Douglas Cobb? His bio is at the bottom. His thoughts on mold seem interesting. He's a real paper/currency forensic scientist. (unlike some who just play one in tv documentaries )

I think Doug could explain the holes in the Cooper money and maybe explain whether the circular hole deterioration, and ink fading can give us any clues.

... Douglas Cobb, a paper scientist and forensic paper examiner, to tell us just how long cash might last


“Money is made from 75 percent cotton and 25 percent linen fibers — often called ragstock or rag paper — while most paper is made from cellulose fibers from trees,” Cobb explains, adding that those critters in the ground would make a pretty hearty meal out of that, so you might find the cash reduced to nothing with 10 or even five years.

If you put it in a suitcase, it’ll last much longer. How long depends upon what the case is made from — the more waterproof, the better. “Once money gets wet or moist, it will start to mold within as little as 200 days,” Cobb says. So, if you pick the right suitcase that’s fairly guarded from moisture, Cobb says it could last “a few decades.”
