In order to better document the coins in my collection I intend to take pictures of them all. Everything from the most expensive to the cheapest. My concern is how to store them AFTER I take the pictures. And by "store them" I mean the type of holder. Right now I'm tossed up between 2x2's and flips. Coins in slabs are no problem; they are already in holders and are labeled. Most of my non-slabbed coins are in 2x2's. To image them correctly I'll remove them from the 2x2. 2x2's are less expensive and do the job. But there is a bit more effort required in putting coins back into a new 2x2. And they make labeling more difficult. Flips are easier to put a coin into and labeling is possibly easier because of the second pocket. I would even consider printing the labels which would make things neater. But a coin can move around in the pocket resulting in friction wear (the classic slider). I'm NOT considering air-tites at all. Which holder would you recommend I put them into? And why? I'm particularly interested in things I've overlooked.
