Storing Lincoln Cents

AAHHH, yes that is so true. Way, way back I used to use the regular type on everything. Not only does it turn yellow but it looses it's ability to hold anything eventually. Some boxes, papers, 2x2's, etc that I used it on a long time ago have turned that yellowish. Worse yet some of it causes a ugly, gummy as noted, staining appearance on cardboard. Really ticks me off on some very nice collectable items in the original boxes.
Not sure who makes them, heard it was Whitman, but at coin shows they sell longer Red and Black cardboard boxes for 2x2's. Some are only one row but most are 2 rows. They are about a foot long and hold well over 250 of the 2x2's. I've noticed though that not all 2x2's are the same thickness. There are heavy duty ones that take up more space and are harder to insert in those plastic pages for 3 ringed binders. The person at one of the coin shows I go to said there are 3 different manufacturers he deals with and they are all different.
As to staples I just use the standard Swingline ones that are used in most offices. Staples are extreamely easy to purchase for them. Then I just use a pair of pliers to flatten them. Takes a few minutes but no special items needed. Note some or most Swingline Brands of staplers have a removable, turnable plate where the staples hit. One way makes the staples turn in, the other way they turn out. If you find one where that plate is square, you can turn it only part way and the staples will just flatten.
