hello everyone.i was just wondering if cardboard 2 by 2's damage coins.if they dont protect the coin will a marcus air tite work better.
Hello Schanky, Welcome to the forum! With care of handling, both will store well for long term. 2x2 cardboard with mylar film. Mylar will not harm coins. Staples are usually the culprit. Those that are not stainless steel can rust after 5-20 years depending on the humidity, and affect the enclosed coin, and they can damage adjacent holders if the tips are not firmly pressed flat. Can be easily written on and are usually less than 3 cents each. The Marcus is non-reactive plastic also. The plastic is hard enough to scratch coins also if not handled properly. They are not air tight ( nor are airtite brands) so the same environmental factors that affect cardboard can do so here also. They are a little bulkier, and scratches easier than the mylar. Downfall is that they are usually around 50 cents or more. I have seen 1000$ coins in cardboard 2x2s and 10 cent coins in a marcus type. I would and do use cardboard 2x2 for some inexpensive coins, but prefer 2x2 clear mylar flips for expensive coins that are not slabbed. They are equal to the 2 above, cost just slightly more than the cardboard, and can be heat sealed to eliminate environmental factors, or to send to buyers who might switch coins on you. IMO. Jim
+1 To add to what Jim stated, you can get a "flat-cinch" stapler from Office Max which decreases the chances of an errant staple scratching a coin through the mylar window. Chris
