What Exactly Is A 2x2?

In my opinion it's the 2" by 2" cardboard flips that house a coin.

The term '2x2' (on its own with no other qualifiers) usually refers to the folding cardboard and Mylar* coin holder.

The clear folding all-plastic flip comes in a 2x2 size and is sometimes (mistakenly) called a 2x2 (with no other qualifiers), but 'flip' (alone) seems more prevalent.

Then there are those who say 2x2 cardboard flip (instead of holder).

Confused yet?

In my opinion, it is best to be as specific as possible, so I try to refer to them as 2x2 cardboard holders and 2x2 plastic flips.



* For what it is worth, I generally try to avoid using Mylar as a genericized trademark. The actual material is BoPET (Biaxially-oriented polyethylene terephthalate).

For me, a "2x2" means the cardboard flip (white on the outside) that you staple, although I have used self-adhesive ones in the distant past.

A "flip" is the all clear storage device with a pocket inside each cover and is of the same dimensions.

both are 2x2 and fit in the same pages and boxes, so it really doesn't matter. I usually say cardboard 2x2 or 2x2 flip to differentiate.
