Coin And Currency Set. Fix Or Forget?

The bill would probably have value based on condition, I'd just want to protect it right away (one of those sleeves).
The bill in this set was a unique serial number. Because if the contributions of the Mohawk Iron Workers during the demolition of the Twin Towers site, the bills in the set start with number "911".
Yes the coin is Enhanced Uncirculated.
I can try tapping, etc on edge some more, but I've tried that a lot already.
The bill seems to be sandwiched in between 2 layers of plastic. Trying to get the cardboard cut open where is was glued together may be the only answer as far as trying to repair this. It's not highly valuable, so again I could try that or just decide to leave it be. The thing to do is legally examine how it's assembled more closely.

i remember receiving some that had that issue. I sent them back at the time. It seemed like there was some type of adhesive on the edges. Mine wouldn't budge. I would leave it as is if it doesn't move.

I went ahead and tried.
First of all there is no way it would have moved by bumping, as I'll explain.
The paper part that covers the plastic panels that encapsulate the bill is folded on one side. So using a very sharp (new blade) box cutter, I started cutting on the open (non folded) side to try to open up the cardboard. I got it opened on that side to the point I could get a tweezers on the bill, and it wasn't moving at all. Since it was shifted down, I decided to continue to open it along the bottom edge. What's holding it together is a very sticky sort of tape, almost like a glue strip, it's hard to describe it. But I cut it and the bill was actually "caught" in the glue, which is why I say that tapping wasn't going to move it.
So I managed to free it, and pull it out, but the glue remained. There already was a small tear in the bill from removing it. I managed to get the glue off by sort of rolling it off, but it was hard to do without damaging it. I got the tear sort of put back in place.
I didn't have to reglue it, like I said it's kind of weird stuff and seems to have "rebonded" itself back together.
I'm happier with it back inside the window. So it's both better and worse.



In these last pics I'm pointing at the damage to the bill, it's more noticable on the reverse.

That's what I meant by there being some kind of adhesive holding it together. I remember others thinking the same thing. There must have been many returned at the time.
thanks for giving us results of your experiment.

I would normally put a few drops of 91% alcohol once I have a opening, and continue doing more drops until it split open, lessen the damage.

that 'glue' you mentioned reminds me of something like rubber cement of that type of adhesive that is used to attach a credit card to the card stock it was used to mail to someone in.

All of the ones I bought WAY back in the day had the same issue. I forget exactly what I did to fix them, but there are other threads on CCF regarding this exact issue.
