looking at finally sorting out my collection. I'm curious as to what would be the best to store in- those plastic flips (not the pvc ones but the nicer quality ones) or those cardboard coin holders with the film in the middle, which you staple down. I can see pros and cons to both- with the coin flips it means I can take coins in and out and don't have to worry about the size, however it isn't as tidy (in my opinion) and I'd rather write directly onto the storage. The cardboard coin holders are neater and I can write information directly onto the storage but can't take them out and have to buy different sizes. What are the best options? Also, what brands for each do you reccomend. thanks.
