Do You Reuse 2x2s?

You can always go back later and replace it when you do get some more of the right size.

I don't re-use them, but this thread got me thinking of a movie I saw with my kids recently: Big Hero 6

One of the characters, Fred, says, "I haven't done laundry in six months. One pair [of underpants] lasts me four days. I go front, I go back, I go inside-out, and then, I go front and back."

Anyone that extreme?!

The worse part of reusing them is you just don't know what was on the coin or coins there before. Now the inside could well be something you really don't want on a coin.

I have never reused a 2x2 flap I like my 2x2 to be neat, and with coins in them

Yes. Over the course of many years, I've come to possess enough foreign coins that I thought I might see just how many different countries were represented. I found 90. Some countries had hundreds of samples, so I decided to start a World Coin Collection. My goal is to have one coin from each country, alphabetized in a large 3-ring binder. As I go around to the various caches, I gather the coins, bathe them in acetone, put them in the 2x2 and add a label. Shortly thereafter, I find a bigger and better example to represent Slobovia. I'm now close to 150 countries, behind in my spreadsheet updates, but have recycled many 2x2s. Staples not required (yet) and they are easy to remove for taking pictures.

The only problem has been with small and thin coins - they can shift.

Impressive.
