I mentioned in a previous post that I was going to have to replace lots of 2x2 cardboard flips as a precaution.

Maybe I picked up a trick that will help someone else in the same predicament. Maybe someone will point out something that I'm doing wrong. Either way...

The first thing that I learned is that I stink at positioning the holders in the stapler at a consistent depth and angle. I'm not so bad at side to side positioning. So I made myself a stapling jig / guide. I made mine out of a scrap piece of wood that holds the stapler in a known position and has marks where the guide / fence should be placed. I'm currently just wedging thin pieces of plastic between the stapler and the jig to serve as a fence for the jig. I'll probably replace the wedged plastic with fences mounted in a T-Track as a more permanent solution that can be adjusted based on the window size of the 2x2. If my stupid stapler had sides that were parallel, I'd probably mount permanent fences and adjust the depth of the staple with different sized stop blocks to change the relative position of the stapler. As an added bonus, I'll be able to get a consistent position on the staples 4 years from now.

So the process goes something like this:
1. Pull a row of coins out of the page, reverse side up.*
2. Use a sharp knife to cut around the edge of all of the coins.**
3. Pull out a new cardboard 2x2, swipe the dust off with a clean, lint free cloth.
4. Give the 2x2 a couple of blasts with a hurricane blower for any dust the cloth missed.
5. From about 1/2 inch above the new 2x2, let the coin fall out of the old 2x2 (obverse up).
6. Give the coin a couple of blasts with the hurricane blower .
7. Close the 2x2 to flip it over to the reverse side.
8. Couple more blasts.
9. Position the coin in the 2x2 window with a bamboo chopstick.* ***
10. Close the 2x2, flip it back over to the obverse and use the handy stapler jig to staple all four sides.
11. Crimp
12. Transfer any data from the reverse of the old 2x2 to the new 2x2
13. Repeat 3-12 for the rest of the coins in the row, set them aside for the ink to be 100% dry
Repeat the process for the second row of coins, then flip the first row of coins over and transfer any data to the obverse.
Repeat the process for the third row of coins, at which point the ink on first row of coins should be dry enough to go back in the page.

* I start the process with the reverse side up because I've been working on US nickels and I find it easier to position the nickels in the window using the straight lines of Monticello than the random head tilt of Jefferson. It also matters that I'm using the hurricane blower on each side of the coin.
** I've been putting coins in oversize 2x2s (nickels go in quarter size, cents go in nickel size, etc), which leaves plenty of room to cut around the edge with a knife. Obviously I go a different route when the coin is in the "right" size 2x2.
*** Yeah, I know. There's probably a better choice for gently moving a coin around than a bamboo stick, but it was handy and clean and not my finger.

Hopefully this is useful to someone,

That sounds like a ton of work. I think we are going to need pics of this contraption

I too am interested in the construction of this handy stapler jig.

Also a flat clinch stapler would maker this more efficient by obviating step 11.

Interesting.

It seems you find as much enjoyment in creating and documenting the process as you do with the coins. That is a good thing.

Here are the images of the contraption. My wife would laugh if she knew I was posting pictures of a jig online. I'll make a jig for just about anything - I've even been known to make jigs to help make other jigs.

Evidently the piece of scrap I used was a little too scrap, I didn't leave myself enough room to install the T-track. I'll have to figure out some other way to mount permanent adjustable fences - maybe a through mortise held in place with a wing nut. Although the business cards wedged in the gap is getting the job done for now. And there's really no reason to make another one until I decide about the flat clinch stapler. I tried to find a replacement anvil/striking iron for my stapler, but with no luck.

I have a three staple method thereby saving one staple per flip.

I like it, thank you for the pictures. I also use a 3 staple method, which I suspect would require modification to the setup shown here.

After recent scratching of the mylar from staples in adjacently stacked flips, I'm starting to consider going back to 4 staples which would let me staple farther from the coin to avoid scratching the mylar of other flips while keeping the coin secure.

This looks like a great method for keeping things neat and tidy looking though! I like these kinds of little projects too, even if it's not always necessary thinking of an optimal solution is fun.

What is a hurricane blower? Do you mean canned compressed air? That stuff usually has chemicals added to make it unpleasant for people to inhale. The chemicals may effect the coin.

What I called a hurricane blower probably has a proper name that's not hurricane blower.
It's the opposite of a snot sucker (nasal aspirator) for kids.

In general, you compress a soft bulb and it expels air at a rapid rate through a directional nozzle, usually sucks air back into the bulb through a valve at the other end.
Great for cleaning the dust off cameras (and 2x2 cardboard flips, and coins).

You could definitely adapt this to staples at 45 degrees.

The first thing that comes to mind is to put 2 posts closer to the user for the two 45 degree staples and use the already existing guides for the single 0 degree staple.
The posts would need to be somewhere between 2 and 2.8 inches apart - enough room for the 2x2 to slide through square but close enough together to catch the corners when turned at a 45 degree angle. Exact positioning would depend on lots of factors, most importantly the depth you want the staple. This setup would definitely take more tuning.

For this kind of setup, I'd want to be able to adjust the position of the stapler instead of the fences so that you could adjust the position for different size windows. In which case you'd really want a stapler with parallel sides so that it could be moved forward and backward and positioned with stop blocks.

Here's me holding 2 chopsticks in place to give you an idea of what I'm talking about with the posts. 1/8" wooden dowels would probably work best in real life.

This is a very neat way of stapling! I used to staple my coin holders, but the often the plastic sheets I put them in were so tight that the back end of the staples ripped the plastic. Since then I use the self-adhesive ones. Anyone recognize that problem?

The pictures are great, thank you for sharing.

I like what appears to be an intersection of two hobbies that you have.

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.
