How many staples do you use when securing a coin in a 2X2 flip? A very telling question I understand...
For large coins I use 4, for the smaller ones I use 3 in a triangular pattern. Of course, I flatten them all. The primary aim is to make sure the mylar is stretched tight over the coin.
I stopped using cardboard flips because of the staples. I use a combination of other things - from airtites to cointains in saflips.
I'm making the switch to Mylar and airties for my "before being graded holders". Right now, I use 3 staples on 2x2s that hold Lincoln Cents. All my other coins are in special holders. I voted "other" because there was no WTF?!?! option.
I use 3 and that works well for me. I also flatten the staples so they go into a box without sticking to other ones. NOW what I don't like is when dealers use 5 or 6 staples. Do they think this is making them safe? The reason this makes me a little on the hot side is I bought a 1921S Lincoln Cent in MS60 or better in a 2x2 with 6 staples. I used a screwdriver to pry out the staples. Needless to say it slipped an ran accross the face of the coin. Not my fault I told myself, it is the dealer with all the staples.
Zero-I don't use 2x2's. :hammer: I always figured they were just a low cost way for dealers to sell coins. They are not air-tight or attractive. What's the point?
Four. With a specially dedicated pair of needlenose pliers to flatten the staples. I even remount coins in "fresh" 2x2's when I buy from dealers. Everything must match. (Anal, aren't I?)
Scant - careful with that glue. I'd imagine that most glue contains chemicals that release gas. Sealing up a coin surrounded by glue can cause artificial toning or even surface damage over time.
Dont use staples as the mylars I buy are the sealable types, I worry about the posible corrosion from the staples, also slowly moving into Airtites. De Orc :thumb:
Outgasing from the glue can be much more harmful than staple corrosion, especially since the corrosion wouldn't physically contact the coins unless the staples themselves touched the coins.
