My Process For "Re-Flipping" Lots Of Coins In 2x2 Cardboard

qxy, I recognize how this could happen, if the back ends of the staples protrude and the flips are thicker, especially for some of the dollar coin flip holding thick coins.

My best prevention strategy for this would be to either flatten the staples as best you can with pliers or to invest in a flat clinch stapler for stapling flips. I made the switch a few years ago to a Max flat clinch stapler and am very glad I did. Flips look neater as a result.

Baltika, my stapling strategy for closing flips with 3 staples is staples at 2, 6, and 10 o'clock, with the folded edge of the flip closest to 12 o'clock. So the angle of the edge of the flip to the staple is either 0 degrees or 30 degrees, depending on which staple.

I'm not sure how you might achieve this with a jig, but it's probably not worth it to save the cost of a few extra staples compared to the 4 staple method lol

I had to replace quite a few mylar / cardboard 2x2's with new ones, because they were housed in soft PVC album pages.
A severe problem arose because the 2x2's were sticking, and were sometimes were impossible to remove, from the album pockets.
The only solution was to replace the PVC album pages with Mylar, or clear polypropylene album pages.
Polypropylene album pages do not have any oily plasticizer to leach out and redeposit between the outside surface of the 2x2, and the inside surface of the album pockets. Over a thousand 2x2's had to be replaced - quite a large job!

Polypropylene and Mylar album pockets do not hold the 2x2's so well as the PVC album pages; the 2x2's can fall out if the album is not handled carefully.
The solution to this problem is to curve clinch the staples, thus effectively increasing the thickness of the 2x2's. Such an approach provides a reasonably effective way of stopping the 2x2's from falling out of the album.

With small diameter hole 2x2's (for dimes and pennies), I usually use three staples only, equally spaced, and quite close to the hole. This prevents the coin from moving around inside the 2x2.
With dollar sized coins in 2x2's, I use eight staples, closely overlapping lengthwise (not side by side), two per side. This stiffens the cardboard at the four thinnest places on each side.

Do you have any pictures of the 8 staple dollars?

That's also interesting information about the polypropylene pages not holding the 2x2 holders well - so you curve clinch them. I'm ordering a box of 100 polypropylene pages soon, and will stop flattening the staples until I get the pages - that could save a lot of time and a could determine whether investing in a flat clinch stapler makes sense for me.

Thanks for the info!

You envision a set screw sticking out of the front...of what? The stapler, or the jig? :)

For this setup to be functional:
Since the fences/posts are fixed, the position of the stapler needs to be adjustable
For the stapler position to be adjustable, the sides of the stapler need to be parallel
Some kind of set screw for the front (this is not clear in my head), or a stop block behind the stapler would make sense to adjust the point "S".

In my head, I'd make the seat for the stapler long enough so that the point "S" and the line "Y" intersect. Then I'd make stop blocks of certain sizes to put behind the stapler, pushing the stapler (and point "S") closer to the user. Large dollars might get 1/16" blocks, quarters might get 1/4"...

Of course I'd never use just 3 staples on a 2x2...so this setup is all just academic for me. If anyone actually makes it, I'd love to see a picture though.

I ended up making the jig, just to prove to myself that it would work.
Took about 30 minutes. My inner OCD child is sated for the time being.

Make a jig for the hole placement. 2" piece of scrap, it pivots on a wire nail with a 1/8" hole about 1 1/4" from the pivot
Layout the two 30 degree angles with a protractor.
Tack the hole placement jig in place and use it to drill the 4 angled holes
Measure up 1" and drill two holes just barely wider than your stapler
With the 6 dowels in place, you're ready to find the right stapler position (in my case the dark red line indicates the front of the stapler position)

The pages that I ended up with are the 20 pocket polypropylene from BCW and they do not have the problem with my 2x2's wanting to fall out if not handled correctly. I do know that my 2x2's are not really 2"x2", they're really 2" x 1 15/16". If I turn my 2x2 sideways, it is rather loose in the pocket and would be apt to fall out if not handled correctly.

Perhaps the 2x1.9375 is a common "design"/"flaw" and switching the orientation of the 2x2 would allow you to start flat clinching again? Assuming that you *want* to flat clinch or the added step of crimping with pliers.

Hi. Greetings from Ukraine. I have made 3D printed stapler jigs for all sizes PCCB cardboard holders. Do you like tis?
